I want to get into "hobby"-mining. Questions about which GPU to buy! (Also, I am a Gamer and YouTuber!)

Good day everyone!
My old AMD HD 7970 broke some weeks ago and I intend to get into mining. But not 24/7, just for the fun of it. I do not view the price of the Graphics Card as a cost I have to calculate, because:
  1. I need a GPU to play games
  2. I have a active YT channel with over 2m views and 5k subs, and I need a good GPU to record and grow!
So if I do not use the GPU (which will be around 80% of the entire day) I will leave it on and mine.
Why? I am doing this because I want to support the decentralized network. I would not mine Bitcoin because huge ASICs are killing the idea of everyone mining individually. My support is little, but I like it.
So because I want to play games as well, I have to eliminate certain options. E.g. given the GPU's have to be the same and support SLI.
I have these GPUs in mind:
Arguably I need nothing more than one good GPU, so the SLI-Setup would indeed cost me extra money. But hey - I will have more FPS and in the future I planned to make a 3-Monitor setup to play games. So it does not matter!
I need more information about the performance of these GPU's. Any advice would be appreciated!
EDIT: Like how are the differences between the mining performance of these cards? I read somewhere that GDDR5X is not so good for mining, for example. All of these cards are enough for my (current) needs, and will also probably be for a long time. But as a gamer - you can never complain about more FPS!

Having trouble finding drivers for my AMD HD 7900 series graphics cards on Ubuntu 16.04

I recently wiped my old bitcoin mining rig and decided to re purpose it for training my ML models. Unfortunately I have found that the open source drivers which come with the install do not work very well for me. When I try to stream a youtube video for example. My computer can't reach 1 fps, seriously, it updates parts of the screen like a terrible composite slideshow.
I have 2 AMD Vapor-X HD 7970 3gb DDR5 cards. I should at the very least be able to stream a video on my computer.
I have tried installing different drivers for Ubuntu including the fglrx driver for generic linux distributions, but without fail, my computer gets black screens and low graphics mode messages when I reboot and it senda me to an infinite login loop.
I have been reinstalling Linux each time since it doesn't take that long and I have no valuable data on here yet anyway.
Also, I have tried Obiaf's open sourced drivers and that turned my computer into a glitch art generator.
Is there another more advanced way to make these cards useful? It's hard for me to believe they are already obsolete. I am willing to go to extreme lengths I just don't know which direction to begin moving.
Thanks for any help

no post craping on this item unless you can find a cheaper one online

Pricing this one is abit on the difficult side but i figured i would start here and go from their.
This is a BEAST of a motherboard supports dual socket 2011 cpus and is the only mobo for this socket that will let you overclock them (bclk oc) I currently run dual e5-2670's on it and it handles every task i throw at it with flying colors. I have tested it with MANY operating systems including, 2008, 2008 R2, 2012 R2, win 10, ESXI 6.0 (majority of time), and Proxmox (basic testing) all of which it was COMPLETELY stable. However, this motherboard does have some damage in both of the sockets. socket 0 is missing 3 pins all of witch are redundant I believe they are all grounding pins. socket 1 is missing about 5 and some of those are redundent but some of them are related to dimm 4. dimm 4 of socket one does not work leaving you with only 11 out of the 12 dimms. This is the only damage that effects the functionality of the mobo the only other "damage" is VERY small and in no way effects the preformance or look of the mobo. Currently this is the only on I could find for sale anywhere and figured i would put it on the market in case anyone was interested. This is used in my daily rig and i use it for everything from virtualization to CAD and gaming with zero issues.

would like to keep until i sell the sr-x as its a important part of my main rig.

Not So Brief History of my Radeon HD7950 ASUS Direct CU II

Sexy Beast Pic 1: https://i.imgur.com/dQC90.jpg
Sexy Beast Pic 2: http://www.legitreviews.com/images/reviews/1839/7970-dc2-top.jpg
ASUS HD7950 Direct CU II. This card mined 1.5-3 BTC Bitcoin for me. Started with Bitcoin, then mined Litecoin in the early days of Litecoin GPU mining. Had 2 X ASUS HD7950s running 24/7/365 at the time. Each did about 3 BTC each total, and then switched full time to LTC Litecoin. This card was also used for CS gaming, 3D rendering, real time graphics, some video editing, and yes, yes more mining! Still RUNNING today! AMD FTW!
After some test mining Litecoin for a month, I quickly built 2 more Radeon GPU rigs to mine LTC. Total 3 rigs 12 cards. Blazin! Then in Dec 2013 this setup mined millions of Dogecoin in a few days shortly after launch,... I remember raking in over 300-500K DOGE / day at full throttle. We setup our own Doge Pool, and DOGE miners were chatting on IRC: The Excitement was REAL!
This fun SUCH DOGE WOW time was cut short by a massive ice storm that knocked out the power for a week. So no more DOGE. When I got back online diff was up and production down to 30K per day or less, but DOGE price skyrocketed so I sold DOGE for a good profit.
I remember donating DOGE to send the Jamaican Bobsleigh Team to the 2014 Winter Olympics, and they made it to Sochi! What a time to be alive! I was a DOGE Millionaire by then... Such Card, Much DOGE! WOW!
Shortly after that, around March 2014 the second HD7950 blew some caps and need to be sent to ASUS for service. ASUS promptly replaced the card under 3 year warranty and shipped a replacement in two weeks. Mining frenzy continued with FeatherCoin and PotCoin. DGB Digibyte was the next chapter! ;]
In summer 2015 I decided to part with one of them. Sold on Kijiji to a local fellow gamer that had his video card blow up, and didn't have enough $ to buy a new one. Gave him a deal. The guy was so happy, it was like Xmas for him. I knew that this ASUS 7950 will have a great home. So I said Good Bye to engine #2.
When this card is retired I will box it for display. Been through so much with it, still my number 1 engine. When something is this good, you keep it in the Fam'. Still works great. Thank you ASUS & AMD for making kick ass products! Over & Out! Peace! ;]

A disgruntled opinion/rant regarding Bitcoin/Litecoin/etc. mining and the enthusiast GPU market.

Back in June of 2012, I very eagerly built my rig with a single Radeon 7950 in anticipation of crossfiring it down the road with a 7970. Now that time has come, and in my efforts to procure what I had anticipated to be quite the bargain, I am absolutely flabbergasted by what I discovered.
There's not a decent Radeon 7xxx in sight, and the 7970s that I could find are going for upwards of $400 USD! This is simply unacceptable for a two-year-old card, and even more unacceptable when considering that these very cards were (according to this guide) retailing for $269.99 this past October! That is nearly a 50% price increase in just two months at the very end of the card's life, and just after the universal price drop to all 7xxx units complimenting Nvidias launch of their GTX700s.
I hope I'm not being oblivious/naive here - and please correct me if I am - but I have NEVER seen that happen before with ANY consumer product (that is being replaced by a new revision). Of course I know the economic rules of supply & demand: There are lots of people who want these few cards, so AMD can afford to boost the price on them. However, this is pretty unreasonable considering AMDs focus on the new R9 chips, which are the new supply.
The perpetrator here is the growing trend of Bitcoin mining. The computing power and efficiency of AMDs GCN architecture is extremely good at mining for this "magic internet money." A growing amount of people are noticing this, and thus demand for AMDs chips has blown up like crazy. It's even become a goddamn selling point in advertisements.
I understand that the processing power of these cards can be very well harnessed for coin mining, and that's fine. However, for those of us enthusiasts that enjoy using our video cards to push pixels, I anticipate this trend to continue putting a strain on the market and our wallets.
TL;DR: I'm butthurt about last-gen AMD GPU prices being unreasonably high, and get mad (within reason).
*edit: AMD is not boosting prices, retailers are. Thanks to Shrederrr for clarifying.
**edit: To all the people suggesting that I sell my 7950 on the secondhand market, thanks; that is a good idea. Honestly the solution didn't cross my mind at the time of making this post - I was still reeling from the unbelievable prices and frustrated that I wasn't able to follow my planned upgrade path. This unprecedented Bitcoin/Litecoin phenomenon caught me by surprise and it saddens me somewhat to see these enthusiast GPUs being used in such a menial, greedy fashion. It's like seeing a Ferrari V12 powering a backup generator for a t-shirt factory. Sure it's being put to good use, but it's just...not right.

[Troubleshooting] GFX issue or CPU issue?

I've had my HD 7970 for a while and after mining some bitcoins with it, I had some artifacting, and some occasional graphics "hiccups". Lately it has gotten bad enough where I finally decided to confirm it as the root cause. I ran 3DMark while watching my temps, and to my surprise, my graphics card only got to 60C while my CPU got up to 103C! This was while running the Time Spy test.
My graphics drivers are up to date, and I'm running an i5-3470.
So I'm wondering if I should instead be replacing my CPU, or if anyone else has another test I can run to confirm one way or another. Would running a load test with the built in graphics be a good test?

Get my mining rig to boot, I'll pay you +$30 in bitcoin right now!

Whoever get's my mining rig to boot up and get mining properly, will be sent +$30 in bitcoin instantly from my coinbase account. I have bitcoin ready to be sent as soon as my system is up and running. Please take a look at the info below and reply with a solution! First person to fix my rig will be sent the bitcoin!
The setup:
MOBO: ASRock Fatal1ty Z87 Killer LGA 1150 Intel Z87 CPU:Intel Pentium G3220 Haswell 3.0GHz LGA 1150 PSUs: 2x EVGA SuperNOVA 1000 G2 80 PLUS GOLD Certified 1000W GPUs: 2x SAPPHIRE 11197-03-CPO Radeon HD 7970 3GB 3x GIGABYTE GV-R928XOC-3GD REV2 Radeon R9 280X 3GB Memory: 2x 4GB DDR3 1600mhz Corsair Vengence Other: 16x and 1x molex powered risers, add2psu adapter
I have three gigabyte windforce gpu's and two sapphire 7970 cards. For some reason I cannot get my rig to boot with 4 gpu's or more. I got my rig to boot into win8.1 a day ago with 4 gpu's but after restarting it, It refused to post again. I have risers on all the slots and have tried configurations with the gpu's in different slots. I have jumped the A1 and B17 pins on two of the 1x pci-e slots (last two 1x slots furthest from the cpu) and jumped the A1 and B81 pins on three 16x pci-e slots. I've tried configs with two 280x gpu's on 16x risers and with two 7970 gpu's on 1x risers. I've also tried three 280x gpu's on 16x risers and one 7970 gpu on a 1x riser. I've tried many similar configs but I have had little to no luck. Im using dual psu's with the add2psu adapter. They're the same evga 1000w psu's. All the risers are powered too. And I do receive 5 beeps as an error code through the mobo speaker when I try to boot sometimes. If not, the fans just get loud and the system never boots. All the graphics cards are plugged into the primary psu and so are all the molex cables powering the gpu risers. The second psu only has a single 24 pin cable being plugged into the add2psu adapter.
Working solutions will be rewarded! Thanks :D

Radeon HD7970 question about fan speed and overclock

A little help with over-clocking a my GPU, a reference design Sapphire HD7970.
I'm using my HD 7970 to mine bitcoins. Before today, I was running it at stock settings and speed. What bothered me was that cooling profile behavior. It would let the GPU warm up to about 93C while keeping the fan at less than 70%, then sometimes go to 95C, which forced the fan to spike up to almost 100%, which caused the noise to go way up too.
Today I installed a python package called ADL3, which gives me fine control over clock speeds and fan, so I started to play a bit. By setting the fan at a fixed 75%, I got to keep the temperature at less than 80C, so I decided to over-clock it a bit.
now I'm running with this settings:
I got a little more than 10% extra performance while mining, but I believe I can get even more if I go higher.
So my question is:
What's the long term consequences of running the fan between 95 and 100%, unattended, for extended periods of time ? And by that I mean 12 hours a day 6 days a week ? Will it reduce the useful life of the colling system and cause me problems ?
What impact would this have on the GPU itself ?
Edit: AllPeopleSuck suggested Saphire Trixx to control the cooling profile. I'll try that when on Windows and use ADL3 and some scripts when on Linux. thanks everybody.

[USA - MD][H] AMD GPU's, Seasonic PSU's [W] Nvidia GPU, Multicopter Parts, GoPro, Paypal, BTC

I have several GPU’s and PSU’s that I am looking to trade or sell. Everything is still under warranty. The cards were used for mining from the purchase dates (listed below) through April of 2014, then I moved and never started mining again. All the cards have been very well maintained, temps were in the mid 60’s generally (except the reference 290, it was in the high 70’s). Fan speeds were generally around 50%; I had the miners in an unused/unheated room with fans venting the air out, so everything was nice and cool. They got cleaned/dusted at least once every few weeks.
Prices include shipping to the continental U.S. I will take Paypal, Bitcoin or trades for the stuff I am looking for listed below. Feel free to make offers with other stuff as well. PSU’s:
1000W Seasonic Platinum - $185 Purchased 05/13 http://i.imgur.com/Jc4Rk3O.jpg SOLD
1250W Seasonic Gold - $185 Purchased 12/13 http://i.imgur.com/xuSuFpG.jpg
GPU’s:
MSI R9 290 Reference Cooler - $250 Purchased 12/13 http://i.imgur.com/xE1X9gS.jpg
MSI R9 290 Twin Frozr Cooler - $270 Purchased 12/13 http://i.imgur.com/uStzTSu.jpg
MSI 7950 Twin Frozr (7970 PCB) - $145 Purchased 11/13 http://i.imgur.com/IQgJakE.jpg
As I said, I am willing to sell outright, but I am also interested in trades. Here are the things I am looking for:
Nvidia GPU – I have a need to do some image processing and the software I’m using needs CUDA. I could throw in a little cash with one of the cards, depending on the GPU.
MulticopteRC parts – I am interested in any muliticopter stuff, especially FPV setups or quad/hex kits, controllers/Gimbals etc…
Fixed wing RC aircraft
GoPro Camera – Interested in all models
Canon Point and Shoot Cameras.
Occulus Rift
Edit: Updated prices based on feedback. Thanks.
Edit2: Also looking for SSD and/or HD and an AMD FX 8XXXX series CPU.

Don't listen to anyone who says XFX GPUs are junk; maybe their firmware is, I won't argue that... but using the Gigabyte BIOS above I was able raise my hash rate to ~700 on each card @ 1000/1375 using around 450 watts, vs. ~550 on each card @ 1200/1500 using around 650 watts on the stock firmware!

[HELP] My Gigabyte HD 7970 can't get more than 420KH/s!!!

So I've started mining with an HD 7970 Gigabyte OC Edition (Dogecoin mining) and all the people I ask and all the information sites I vist suggest I should be getting somewhere between 700 and 750 KH/s with my card. I've tried everything I can think of, upping Memclock, thread concurrency, maximizing my intensity (20), even putting my gpu engine up to 1000 in the .bat I use. I've found that using this .bat setup delivers the best performance.
Please if help me figure out what could be causing these problems, they've been consistent with all forms of crypto currency (Litecoin, Bitcoin and Dogecoin)
EDIT: I feel I should mention I am no expert in coding or overclocking and have next to no experience with mining. Also, my GPU is the overclocked edition so that might be causing problems.
