nope... on tomshardware somewhere there's an article on how only three GTX285s "unleash the i7's true potential". my point being most graphics cards are actually bottlenecking the i7
It probably will "bottleneck" on older single or dual threaded games at 1920x1080 or lower resolution but your frames per second should be of the charts so it doesn't matter. i7 920 @ 4GHz is just about as good as it gets CPUwise so you're going to be maxing out anything at 60+ fps even if it bottlenecks.
