I read that a dual or triple core may be preferred for gaming over a quad core. why is this? i'm looking at costco and sams for a better computer and saw an HP media center m8457c PC that has amd phenom x4 9500 quad core (5120mb 640gb 2.20GHz 5gb). Should i look for a triple core instead?
Also, would the nvidia GeForce 8400 HD work or should i go for better?
Also, if i don't custom built one with the better graphics card, will i have performance problems when WotLK comes out?
My game style is that i run WoW, itunes, and have my research sites open - allakhazam and wowwiki and sometimes thottbot too.
thank you in advance for your comments and suggestions!
