My System Specs

Default gpu + cpu bottlenecks? dual 7850 in crossfire and i5-3570k (when it launches)

i just heard about this phenomenon and it's beginning to worry me.
i have a new build planned for june and it involves:

cpu: intel core i5-3570k (assume i5-2500k performance since this cpu isn't even out yet)
gpu: dual hd7850 in crossfire

will my cpu bottleneck my gpu setup? because that gpu setup is pretty powerful, i think.
i also plan to oc my two gpus like this: 1ghz core and 1.3ghz memory, so the graphics will be a powerhouse

if my cpu DOES happen to be a bottleneck, will a cpu oc fix it?

additional info:
- i will run everything at 1920x1080
- both cards will each have 2gb of gddr5 memory
- i will probably use an asus p8z77-v (8x 8x pci-e gen 3, so no bottleneck there)
- i will use either a 120 or 180gb intel 520 series ssd (or 330 series if it has good value when it launches)
- 8gb (2x4gb) of 1600mhz corsair vengeance lp memory 9-9-9-24 and 1.5v

I highly doubt you have anything to worry about. Maybe if you had an old e4300 dual core. But not the new gear.

If you're overclocking your CPU it shouldn't be a bottleneck.
