I'm going to be building a new machine very shortly and am not sure what procdessor would be the best for me. I will be playing some games on it, as well as just email stuff and internet surfing. The most intensive program i will be using on it will be AutoCad 2009. Now, I've been looking at the E8400 as well as the Q6600 and the Q8200 processors. Do very ma ny games even take advantage of 4 cores yet or would I be best to get the E8400 whick is very overclockable from what i've read? If I do go quad-core, should i go with the newer 8000 series over the 6600? Thanks for the help.
