4K Gaming using two HD 7950

Is it possible to play game at 60fps with two AMD HD 7950 cards? I want to play games like GTA 5, Alan Wake, The Division, etc.

I have a DisplayPort to HDMI 2.0 4K 60hz adaptor by Club3D.
 
I used to have an overclocked 7970 crossfire setup which was between a 980 and 980ti performance and GTA 5 could run at 60 fps in 1440P. At 4K you would be looking at around 15-30 fps imo judging by how the 980ti runs at that res in the newer games.
Lowering detail settings could get you higher but 50-60 fps is not easy even with the top end cards.
 
Think of it this way:

4K is four times the pixels of 1080p.

Can a single 7950 drive those games at stable 60fps at 1080p? Nope.

So can two 7950 (especially crossfire doesn't always work for all the games) drive 4K? Nope.
 
Gotta love this place.:p

Will 7950 CrossFire run titles@4K with the HDMI 2.0 adapter?

If the adapter works as advertised, and as PC titles have scalable settings, then yes 7950 CrossFire is doable@4K on appropriate settings, just be realistic with the settings.:)

Considering crossfire doesn't work or work well on Nvidia titles like over 90% of the times, it's not really worth the trouble...
 
True, I should know.

Pretty vague op, but going off the premise that they didn't ask about adding another 7950 for 4K CrossFire-I'd have said don't do it.:p

But went off the presumption op already has 7950 CrossFire, then they'll know how well CrossFire runs-or doesn't already, res won't reduce scaling they'll just get lower fps at the same settings.

Loads were using twin Titans@4K and probably weren't maxing out vram on most titles-it probably needed 3 or 4 Titans to max out the 6Gb@4K, 7950 is probably as fast as a Titan now.:D

It isn't Division or GTAV, but BF4 on a 7990(which perform very similar to twin 7950's), with 60 fps min on BF4@4K on medium settings

Steering clear of MSAA and the 7950's will do ok on suitable settings in a lot of titles on 4K.
 
depends on the game but, i would not run 7950s at 4K unless your playing game like LoL or Dota


heck i have a 4K gsync & don't even want to run 980s at 4K until i get pascal the hit from 60 to 45 you really feel much more at 4K. I think its more the input lag feel as you got much more distance to travel @4K so 45 vs 60 is much more noticable.
