The 7950GX2 still appears to be only using one card under Vista, even with the very latest drivers. So, it's time to upgrade. What you guys say is the best option. 1x 8800GTX or 2x 8800GTS? It seems cost effective to go GS in SLi, but I'm also very aware that the next round of cards are due very soon. I'm unsure what to do :S
