It all depends on what you play. i have a q6600 with gtx560ti and I know I'm bottlenecked. In Witcher 2 sometimes my gpu can max out at 98%. While BF3 it maxes out around 50-60% and frame rates are abysmal. Always laggy is what I mean. But I manage to get pretty good despite the lag. Now that I'm close to my new build, I'm ready to see what a new system would feel like.
