I disagree based on this review. http://forums.slizone.com/index.php?...pic=23084&st=0
If you are deciding between (2) GTX 280 SLI vs (3) GTX 260 Tri-SLI since both setups are priced the same, I would get (3) GTX 260s. Scaling is quite good on these cards, much more than previous generation cards.

I don't like the performance of the 4870x2 in Crysis. yeah I know it's one game, but there is nothing out there that comes close to the level of graphics this game displays, especially with everything cranked in DX10 mode. This game shows off the true horsepower of your card.
