Well I still say my friends card is better. You better compare the specs.
XFX 6790 Core Clock 800 just for starters And most important LIFETIME Warranty. $149.00
Sapphire 6850 Core Clock 775 1yr Warranty $165.00 on up.
There's enough Specs on both cards at the TigerDirect link if you just compare the numbers "like Core Clock"
to figure out the way to go. Don't go by the model number and think it has to be better because it's higher.
Fell free to ask me any questions.
