hey guys I'm planning on upgrading my gpu from a hd 7770 to a gtx 760, my cpu is an a8 3870k clocked at 3.2 ghz quad, I am planning on upgrading my cpu in the future but for now will the a8 and gtx 760 work nicely together? If there is a bottleneck I think it will be barely seen, let me know your thoughts, thanks.
