get the q6600 from ClubIT they guarantee it
we don't recommend 4gb to gamers, we usually recommend it for Visual Designers and CAD users
Would I lose performance for gaming? I will also be using sony vegas to make videos of games...so maybe 4gb would help there. If it's only 80$ more I don't mind spending the extra money.
I also run x-fire, ventrilo, winamp, web pages, and all that good stuff in the background when I play games...so the extra memory could help.
Q6600 is sold out on clubIT.
