The E8400 @ 3Ghz will be a bottleneck for the GTX 660.
Here is a benchmark with the E8400 and 5870 that is weaker than the 660:http://forums.anandtech.com/showthread.php?t=2059982
In most games the E8400 OC @ 3.9Ghz get better FPS than E8400 @ 3.0Ghz, and that is at the resoluion 1920x1080. At lower resolutions the botteneck will become bigger.
A balanced GPU for the E8400 @ 3.0Ghz is in the performance level of the GTX460.
So you can OC your CPU or buy cheaper card for no bottleneck.
