ASUS or EVGA

Performance is the same, drivers are the same, EVGA has the best reputation for service and warranty support.

Agree with benski.

If you don't plan to OC cards, look to which have the best factory OC and then at prices and warranty period for specific cards that interest you. EVGA cards in general have been having a lot of rebate offers on newegg that might lower price a bit too.
