Meh, I think most of it is kind of a waste of money for such a small upgrade.. Paying $100 mainly just for looks on the mobo is kinda dumb (imo). Even if it's just $50 (oh and Sapphire rebates are pretty much retarded, go read it), not sure if the graphics upgrade it worth it, especially since you're happy with performance right now. Also, the XT is mucho loud. I still wouldn't get a Rosewill psu but that's just me..
Just my opinion..
