Look into either EVGA or MSI. I'd say they're the best brands.
MSI has some excellent cooling systems with their cards while EVGA usually has "Superclocked" cards
Looks like you're going in the right direction.
Evga is a good brand, however they only sell Nvidia cards. You can't really go wrong with any of the board partners in reaility, asus, saphire, his, xfx, etc. The quality of support will vary a little bit, and the pre-overclock varies as well. But any of them sell solid cards.
