The answer depends on how you personally would define 'bottlenecking', and how significant the BN'ing would have to be for you to consider it 'a problem'.
You will definitely lose a few FPS vs. someone with, say, a Sandy Bridge at 5.0GHz, on certain more-cpu-dependent games or benches, depending on the settings at which you run them. The lower the settings (i.e. lower res/AA, etc) the more likely it will be that someone with a more powerful CPU than you would get a higher FPS.
What I'm getting at here is that bottlenecking is not simply a function of looking at the hardware. In order for there to be a BN, software must be running on that hardware. The frequency and severity of any BN is dictated by the hardware + the software. Ergo, this question can't be answered "yes" or "no" without your stipulating what test you're running (i.e. what game/bench) and what settings you'll be running it at.
Generally-speaking, you won't have any problematic bottlenecks w/that setup though Edited by brettjv - 5/6/11 at 4:13pm
