Bad CPU hurting GTX 295?
I've been thinking about upgrading to a Core2 Quad or Core i7 CPU as my Core2 Duo E8500 isn't cutting it anymore. I've got it overclocked to 3.56GHz, but I still think it's holding my GTX 295 back. I've been looking at the Q9650 as the price just dropped today by 40%. I can overclock it to at least 3.4GHz. With four CPUs, I should be all set. Is the Core i7 a worthy upgrade? It seems too expensive for the performance gain over a Core2 Quad.
