I'm currently using a BFG 8800GTS 320MB card...works good, no complaints here.  I was just toying with the idea of upgrading for Crysis, etc.  Was wondering if I could get a couple of opinions.  I could grab a second card fairly cheap now and go with a dual card setup OR should I just wait a few more months for the nVidia 9x series to mature a bit and upgrade to a newer single card. Is there much benefit to be had going with the two card setup in this case ?  I have an "old" box that would accomodate the card (and a son that would be quite happy to get it), so it wouldn't go to waste. Thanks !

I would say get a better single card cuz SLI 8800GTS 320MB would be hugely bottlenecked by the VRAM.

Ahhh...good to know.  Perhaps I will hold out a bit longer and see if new drivers make the GX2 a better option.  Thanks !
