AFOX GeForce GTX550 Ti (V2)

Solution
I don't think all the 550 Ti's did SLI (just like some 7770's don't do Crossfire), any way the other guy's right, you don't really want to SLI two 550 TI's, unless your picking up the second one for very very cheap. I would upgrade to a single 7850, or the Tahiti 7870 if you can spend a bit more. Or you could go with one of the new 650 Ti boost cards.
