that depends on the specific games you play and if they do a good job supporting SLI/CFX. It very much depends on the cards you pick as well. Two gtx 550 in SLI are not greater than a 580 for example but two 560 ti are (in most cases), two 570 in SLI would be better than a single 580.. but there is a caveat: the size of the frame buffer of two lesser cards in SLI must be considered and weighed against one strong card with a larger frame buffer. At higher res one needs more vram and this can become an issue for users of multi card configs where the cards used have less ram. For example 560 ti cards come with 1GB of vram. A 580 comes with 1.5GB of ram (or more). If the user games at high res (25X16 or greater) 560 ti SLI will run out of available vram long before the 580 and therefore is not necessarily "better".
