Will my CPU be a bottleneck?

[Joe Williams]

I'm planning on having two 7950's in crossfire with an i5 2500k at stock speed. Will this be a bottleneck for these cards or do I need to overclock/replace it? (Noob question)

i5 2500k stock speed
2 x XFX 7950's
MSI P67a-GD53
8GB RAM
750w PSU
120GB SSD
500GB HDD

Even at stock speeds I wouldn't think any i5 would bottleneck 2 7950s.

The real questions is why would you leave it at stock speeds to begin with?
It definitely wouldn't bottleneck them if overclocked.

It shouldnt but u also may not see full potential, even though the 2500k is still a great cpu without a overclock it may cause a slight bottleneck but might as well get the second 7950, see how well it performs and determine if u should get a new cpu, or new board and cooler to OC

Sounds good! As for why I haven't already overclocked it, I only have the stock cooler unfortunately so I don't want to risk anything.

Thanks for the help.

It will also depend on what resolution you are gaming on. I assume it's not 1080p as 2 7950s would be massive overkill for 1080p.

You really should just grab something like a Cooler Master 212 and overclock. Your 2500k is a beast.

I'm playing on 1080p but I'm not getting 60fps on some of the games that I play.
