Im in the process of buying a new computer and i was planing on getting the E6600 for a while, but just recently i was on a web site that showed benchmarks for the E6600 and the Q6600. The Q6600 was double the E6600 so i was just wondering if the Q6600 is worth the $500 more and will i notice a difference in the 2 cpu's.

 and im getting a 8800gtx, 2 g's of 800ram and a 630 watt power supply. 

Thanks,
