I didn't mean that, not every game scales perfectly with SLI, no?
Sorry your post was pretty vauge.
I mean, a single card is always going to give you the best performance, I don't remember SLI giving the same amount of a boost in every game you play, only certain titles scale extremely well, others not so much.
Yes but if he can get a pair of cards which perform better than a single card which costs more and has the hardware to facilitate SLI it is a good buy.
