i plan on going w. the sli board incase i decide to add another video card later. the reason for the 120gb hd is that i dont dl too much stuff. for some reason i want to stick w/ the x2. if i end up having extra money, going with the 4200+ isnt that much of a difference. thanks for all of your help. also, what is the difference between the psu that i chose and the antec truepowerII. thanks guys!!
