If there were maybe ...5 superb games out right now that would push TriSLI (or SLI) and you got more than a 10-15% boost with each addition of a card then it might be worth it if you had the money to do it on a 24"+ LCD monitor. The best way, and most affordable way to get into gaming is to use a 20-22" LCD @ 16*10 and no SLI at all just one 8800GT or 8800GTS 512 and enjoy the games now then get Crysis maybe a year from now when you've also upgraded your GPU and Cryisis might be worth it, and by that time there might actually be some other games that are worth playing. It's not worth spending the money on a 1KW PSU and 3x 8800GTS-512's just to be able to barely push Crysis on high ultra settings with IQ just for one damn game and have what sounds like a freakin Cessna prop plane in your house with all of the noise. Better to just wait it out and go with that much better single card a year later (IMO).
