So I've had this rig for a few years now.
i5 650 stock speed 3.2ghz
gigabyte p55m-ud4
Kingston 4GB 1333
SLI 9800GT
450 Ultra PSU
Today when I started up Kerbal Space Program in full screen (1920x1080) everything was in shades of green and red. So i took the cards out and put them back in. Then there wasn't even any DVI signal. So eventually I tried running with only one card. It was GPU 2 when I was running SLI. Now i notice less lag in games than I got when I was running them in SLI. How can this be that I get better performance with only one card? I'm getting a new gpu soon but i'm just wondering why this is happening
