Sorry for my newbie question, i have never been a gamer or hardware upgrading addicted so i don't know anything about video cards!
I see the hardware comparison page on the BitCoin wiki and i see that ATI 6990 are the best, is it right?
On some rows i see 6990x2 or 6990x3, what do they mean?
Thank you.
Using 2 and 3 cards at the same time.
Ok, thank you.
I make this question because i found on some shops the ATI 6990 and in other shops i see the ATI 6990 X2.
