personally i like evga. but either would be good as both offer a lifetime warranty in case ur ocing breaks it.
Of the Asus Extreme 7800GTX, BFG Geforce 7800GTX, eVGA e-Geforce 7800GTX, and the Gigabyte Geforce 7800GTX, which would be the best buy?
It will be used mainly for high-end gaming and the CPU is an AMD Athlon 64 X2 4200+. I don't plan on overclocking.
