I currently have an Intel Core 2 Q6600 @ 2.39 for a processor and I recently purchased an ATI 5850, which has yet to arrive.
So I'm wondering if the processor would seriously bottleneck my gaming performance in terms of fps.
Note: I am purchasing a new processor later but I'm stuck with the Q6600 for now.
Well, it is not going to "choke" it!
But as you go up in processor speed from where you are, the 5850 that you have is also going to scale nicely and it's performance will improve as your processor speed improves.
