Re:EVGA GTX 580 together with GTX580 SC Fermi in SLI
Yes, you can SLI an standard clocked GTX580 and a SC Edition GTX 580. The faster card will downclock to match the slower one.
Of course you could always try overclocking your standard edition card to match the SC...but unless your benching you won't really see a night and day difference.
My computer finds cures for diseases and searches for aliens when I'm not gaming...what does yours do?
