Oops. I forgot. I upgraded last year and added another gig of RAM. I needed it with Adobe CS4 installed.
I have Win7 RC installed right now on my Athlon. I'll keep my current SATA harddrive, and upgrade my current IDE to a SATA at a later date. Once the mobo comes in, I'll test the IDE drive. I have heard that the only negative thing about this mobo is a disappointing IDE support. Not a problem for me.
Sometime around April or so, once the funds allow, I'll be adding another 4GB (2x2GB) (there are 4 ram slots on the ASUS mobo).
My current system I'll then give to my younger brother. His system can't even play Doom 3!
