I've listed the cards that I would personally recommend. There are other good models but the GTX460 Gigabyte has an upgraded cooler and a slight overclock. The 5770 Sapphire VaporX has an upgraded cooler and a nice MIR. The GTX460 definitly outperforms the 5770, but the 5770 is still a very capible card. Get what you can afford, but the 460 is deffinitly worth the 200 bones.
