1080p Triple Monitor Set-Up: R9 280 Crossfire or Single GTX 970?

I've recently upgraded my computer and now I've hit sort of a dilemma. First off, here's my current system.

CPU: i5-6700 Skylake
RAM: 16GB 2400MHz DDR4
Mobo: MSi Z-170A Krait
GPU: 2x Crossfire R9 280 3GB, one is MSi, other is Sapphire, both clocked at 970 MHz
240GB SSD and 1TB WD Hard Drive configuration
750W Corsair HX

Anyway, here's my issue. I'm currently running one 1080p monitor centered between two smaller resolution monitors, giving me a total rez of 4480x1080 via Eyefinity. I recently bought two more 1080p monitors to match the middle one, which will be a resolution of 5760x1080, but I have yet to set them up since my desk isn't big enough.

Of course, this setup is for gaming and one of the games I play is GTA V. The issue is with my Crossfire configuration: it gets too hot for my liking. I tried overclocking the cards to 1050 MHz and my master card was reaching temps of 95 degrees C while playing the game under full load. Not good. I've taken the clock down to 970 MHz and now my master is running around 80 degrees, with the secondary around 70.

Even though I only technically have 3GB of available VRAM, GTA V says I have 6GB, but I'm pushing its limit when running the highest possible settings. I'm still getting a decent framerate at the resolution I'm at (45 min-80 max, 55 avg), but there are two things I'm worried about: the higher resolution I'm going to be playing at when I set up my two new monitors, and the temperatures that I'm currently getting.

Would it be worth it to sell these two cards and get a GTX 970 4GB to give me more VRAM for the higher resolution, or am I better off keeping my current setup and roughing it by having to turn down some settings? Since money is an issue, I'm not really considering a GTX 980 unless I find a decent enough price, or if it is ABSOLUTELY necessary for my higher-resolution set-up.

I guess what I'm saying is, would a single 970 give me a little more headroom over my current R9 280 Crossfire setup?

Edit: Something else I overlooked is what about an R9 290X 4GB/8GB? It's a similar price point so I wouldn't be against looking at that as a single card. How does it compare to the 970 in high-resolution gaming, and as well as against my current setup?
 
Solution
Yes. R9 280 performs nicely, even today. One of those cards performs kinda close to a GTX 960. 2 of them should be a bit better than a GTX 980 as long as you give good airflow, and perhaps a bit of OC, maybe 50 Mhz.

So if you're saying that my current setup is as good as a GTX 980, which costs $200 more (I got the cards on eBay for $150 each), there wouldn't be much point in upgrading performance-wise? It would only be a heat issue? If so, I could try to maximize airflow through my case. I still have some open slots for fans, so if I were to solve the heat issue, my setup will perform just as well as a 980 for my purposes?

Firstly I'd ALWAYS reccomend going with a single card vs crossfire or sli due to the problems assosiated with running multi-gpu setups...
If a 980 ti is in your budget I can garentuee that will do what you need it to...
If not, then I think the 980 is your only other single card option, but with demanding games I dont know if that card can run at max setting keeping a decent temperature with three screens...

SLI 970's run similary to a single 980 ti at similar prices, problem is you have to deal with the issues of SLI...

Good luck!

I guess this raises another question: would 4 GB of VRAM from a 290X or a GTX 980 be enough or would I need the 8GB even if I'm most likely not going to use it all? If 4GB would be a bottleneck for my resolution, the 390X seems like the obvious answer.

And yet again, does anyone have any benchmarks of how it performs at 5760x1080 versus my current Crossfire 280s?

As usual, it comes down to the price with me. $650 for a GPU is well out of my price range, especially if it won't be that much more powerful than my $300 setup. I'm all about that price to performance. So far, I haven't had much problem with Crossfire other than the heat issue, and that's definitely fixable since I kinda slapped everything in there and wanted to get it to work as soon as possible. I guess I'll just have to make do with what I have for now and maybe I'll post an update whenever I do get the other monitors set up.

Sounds great!
Good Luck!
