Get an XFX 8600GT or Palit 8600GT, which were 256MB DDR3-based cards,I have a XFX 7600GT(256MB DDR3) in my PC,my friend recently bought a XFX 8600GT(256MB DDR3) for playing Call Of Duty 4 & Crysis @ med settings. Personally I think XFX cards were superb, & gives that geeky feeling but, I heard that XFX has some heating problems(don know if its true, me & my friend's cards were rock-solid). If u don want XFX then try Palit. I'd also suggest that u look for the ATI HD4850. Don know how much it costs, but its definetly better than its nVidia counterparts.........
PS: I strongly suggest that u plz avoid DDR2 based cards, they were total carp, i suggest u buy the most-least expensive DDR3-based card.....(If u can't stretch ur budget very much)
