Ok I have a few questions..first of all I'm currently running two Nvidia Geforce GTX 560. Prior to that I was running two GTX 460s. I have an Alienware Area 51 computer and they replaced both of my GPU's do to heating issues that were causing artifacts while playing games. However, even with the new cards, I'm still have heating issues. I was told that the problem is the nature of the SLI configuration and the fact that more work is placed on the "primary card." Also, I guess when they first designed this system, they didn't place enough fans or didn't place them low enough in the system so the cards aren't getting the best cooling. I received the recommendation to go down to a single GPU, and my question is basically will I see a loss of performance? My concern with going back to one GPU is the fact that I also run two monitors, and was thinking about adding a third. I definitely want to run two for sure, the third I can live without. Will running two monitors on a single GPU be a bad idea? Is there a brand that is better with running dual monitors? I don't plan on doing gaming across the two screens. I usually play D3, Wow or SC2 on my primary 25" monitor and use the second monitor for browing/itunes/other programs. Basically my choice is to keep the dual 560's, or upgrade to a single GPU with 2gb or maybe 3gb. Also, I'm pretty sure my MB only supports PCI Express 2.0, i don't think it's new enough for 3.0. How close would the GTX 580 be in quality to the 560? What do you guys think?
