I have two BFG 8800 GTX cards running in SLI and I was thinking of upgrading to a single GTX 260. I've been searching for benchmarks that shows cards in SLI, but haven't found anything recent that shows two 8800 GTX in SLI up against a single GTX 260. I've had the two card for about a 1.5 years now and they run great. Is the GTX 260 that much better? Is it really going to be worth it to upgrade or should I just wait for the next generation?
