iceq HD 7950 crossfire on Asrock Z77 Extreme4

ibjeepr · Jul 2, 2015

Hi,
I'm finding HIS Iceq HD 7950 boost going for around $150 or less used these days and thinking of doing crossfire.
Can anyone tell me:
1. Will they fit together on my mobo? Looks like it would be extremely close.
2. Based on my system specs below would you recommend it.
3. I know micro stutter was a problem at the time these came out killing any fps gain. Is that still an issue?
4. Would there be much benefit for me? I plan to run at 1920 x 1080, 60-120 Hertz on the monitor.

Thank you!

It should be worth it, yes. Dual cards can perform at as much as an 80% improvement in frame rate over a single card. But only if the game and driver are written for it. There will be some loss of smoothness in certain games at certain times, but AMD has pretty much fixed the M-S issue with the advent of Frame pacing since driver ver 13.8 forward.
Your board does CF at x8, x8 lanes so you should be good as far as bandwidth goes.

clutchc :

Just out of curiosity, do you know if DirectX 12 and windows 10 will have any effect on Crossfire?. With the improvements DirectX 12 supposedly bring I'm wondering if Crossfire will see an indirect benefit.

I haven't really followed it since back in March when I read this: http://www.pcgamer.com/could-directx-12-or-vulkan-apis-make-slicrossfire-obsolete/
But it was just speculation then. I'd suggest a Google search for more current info.
