I saw that the 8600Gt was on sale for $75 and i'm considering buying another one and using them in SLI. Are there any setbacks with SLI? I don't game frequently but when i do i want it to be perfect. I was wondering if it is worth it or not? I am running dual monitors at 1440x900. I like Crysis and if i get another video card i would defiantly buy it. Also what settings do u think i could use on crysis with two of these cards?
