Will two 7950k's be bottle necked by a 3570k (OC a little over 4). Others say it wont, but im reading more and more about Crysis 3 bottle necking a 3570k in a crossfire setup.


TL:DR So I WONT be limited by my 3570k while running Crysis 3 on Max with crossfire7950's?

No the 7950 Crossfire will not get bottlenecked by the 3570k@ stock clock @ 1080p
But could be @ certain games like Crysis3 Skyrim Hitman etc
Overclocking to 4.2GHz or more is recommended.
Crysis3 few levels so demanding that even a 6 core overclocked cpu struggles.
Thanks

With my i5 3550 the only game I found that had a slight bottleneck was Crysis 3 (And that even bottlenecks with a single 670, its just soo cpu intensive haha.)

Every other game I get 95%-99% GPU usage.

I find this answer odd. You say it won't bottleneck, yet point to examples of it bottlenecking.

All CPU's get bottlenecked from time to time in some games, so I agree with your 2nd thought.

I understand your thought. It's not constant bottleneck, but it still does from time to time. The good news is that Crossfire needs a bottleneck to avoid stuttering issues. Either by v-sync, FPS limiter or CPU bottleneck. (Though the fact you need to hold your cards back is not a good thing, but is needed until the issue is resolved).

Mostly correct. Most CPUs will struggle a bit with Crysis, the 3570K no more than any other.
