Because games can leverage these in different ways there is no right answer. For me I prefer a single card because I get hits over the years from clients that went SLI and they wanted me to clean up the mess. If your SLI works, I might not change it till next year.

I have two (sli mode) gxt 660. Sc 3gb graphics cards. I'm thinking of selling them both at 150 each to buy one gxt 970. Or a similar performance gfx card. My question is that is it worth worth it to sell my two gxt 660? Or am I getting more power from these already?
