You suck you fat ass noob, this isn't a celebrity magazine! No one gives a *** about that so usefull info.
Get a quad core
, the newest quad cores can actually easily reach above 4+ GHz, which makes them competitive with the dual cores at the same speed, because remember... If a game can use 2 cores it a quad core will still work well just 2 cores than can/will be used for other stuff like antivirus software and such so you can search your system for badassware while gaming
Because it seems like people are thinking "Hey, quad cores need a program to use 4 cores omgz, with dual x2 core i can play 2 core in gaming, wow gaming i run cool game for super speed overclock quad core suck my ballz!"
Better to invest in a quad core as it will give you more power in the future!
