OK you all have been very helpful the only reason I asked this question was because I am about to buy a new board for my setup i have and was looking into the dual cores I right now have the one I built and a HP with an AMD 64 athlon X2 4200+ with 1gb of ram and sometimes it gets slow. So i'm jumping ship to an Intel and couldn't figure out which would be better with all the multitasking I do. I need to upgrade but keep my budget under $300 as my wife keeps telling me what i have is good enough but the built computer can't handle the games I play and the HP well it's my wifes so i hardly ever get on it but with insite you all have givin me I think I've made my mind up to go with a Core2Duo
