7950's bottlenecking a 8350?

post #1 of 5
Thread Starter 
Any problems crossfiring a pair of 7950's on a 8350 rig? (sig below)

I'll be adding a second card today and just happened to think about this for some reason.

Thanks

You should be fine, I have no issues with a pair of 770s running a little less clock. I also ran a pair of 7950s briefly before i figured out they wouldnt do what i needed, they were otherwise fine on the 8350.

You will have 0 problems with Crossfired AMD Radeon HD 7950's with an AMD FX-8350 as long as you give it a little OC.
