Rebates dont really matter to me. My computer is a dell xps 410, core 2 due 6600 @2.4GHz. 4gb of ram. 64 bit. Windows 7. 1280x1024. My current video card is an nvidia 7900gs. I want a card that can run recent games like, call of duty black ops, star wars, medal of honor, etc. my psu is 375 watts but I heard it could handle good cards. I was looking at the radeon 4850 and gts 250. Any other options?
