Hello this forum seemed to be the perfect place to ask this question, so here it is. My PC has two GeForce 6600s on SLI. I've been thinking about buying another card (like the GeForce 6800GS), however for the time being I can only afford 1. So the question is. Would 1 GeForce 6800GS be as good or better than the two 6600 on SLI? If you're wondering this is the card I have, and this is the card I was thinking of buying.
