Will my processor bottleneck my gpu?

I'm looking into getting a MSI 7850 2gb next month and I'm curious if my current cpu will bottleneck it to the point of it being a waste of money. I have an A6-5400k overclocked to 4.0Ghz at the moment. Thanks for any help.

Is that the CPU you have? If so it seems to me it would be more likely that the 7850 would slightly bottleneck the CPU. Now while I am a tech head so to speak I do not claim to be an expert. I would say shop around for a good 7870 GPU :)

how would a higher end gpu be any better? wouldn't I be wasting more money?

i might want to think about getting a 6670 with ddr3 and getting faster system ram then you could do hybrid xfire and youre system would be very well rounded

Yeah, you'd probably be better off getting a Radeon HD 6670 and running it in dual graphics mode with the built-in GPU on the APU.

The A6 can't use a 6670 I thought. Only a 6470.
