-Feel like this is a pretty good budget build. Open to suggestions to shave a few $$$.
-Chose Vista so I wont have to upgrade later on. Premium or Home Basic?
-Should I get another 2GB? for that price I think I should.
-Any cheaper PSU suggestions?
-How bout the MOBO? seemed good price and has everything I need for the most part. And it is Phenom ready.

Thanks for any comments/suggestions....
