"Weakest link" in my computer build?

Looks nice but i dont really prefer the AMD Athlon series, but i dont get your graphics card? Its very nice but to good for only some itunes scrolling and browsing and such, or if you want to do games too your graphics card is nice but then i would suggest changing your AMD Athlon to a Phenom II :) Thought i also suggest 1000GB because you already have 370GB on songs
