How much do you run that you need 4 gigs of ram? (note ram is completely different from storage memory.... the most ram most systems need is 2x512 mb)
both mobos have a 4gig ram capacity.
if you want hyperthreading, at least get it with a mobo that can support dual channeling along with it ^_~. Hyperthreading allows you to "multitask faster and more clearly"....... I haven't seen hyperthreading firsthand, only heard/read, though my own intel and my own dual channel setup can multitask as quickly and as smoothly as I'll ever need.
