First, go with Evga, I have owned them, I have owned leadtek. Evga is not only made in america but everything Nirvana is correct. Except the AX, DX applies to the Cards by the way. Also to note: Every brand on the market has a "limited lifetime warranty" Even Evga. Meaning basicly If you happen to break your card at fault more time then anyone can count, thant you don't have a warrinty anymore. Evga's stepup program is awesome. If you buy the 7800gt and in 3 months you see a GTX take a nice price drop, you can just pay the differance on the GTX minus what you already paid. BFG does not offer this.
