A brief look at three-way SLI
 

Three GeForce 8800 Ultras. Two grand worth of video cards alone, yielding over 1.7 teraflops of raw shader arithmetic. But will they run Crysis smoothly? We decided to find out.

I have been holding up on playing crysis, because I wanted to play it 1920*1200 with at least some decent 4*aa on very high...
however, seeing that three 8800 ultra's do not do the game justice, and at these settings yield 27 average frames, going in the ten's...I guess I'll have to put it in the closet till 2009...

by 2009 there will be games which make Crysis look like Pong ;)
