I have a 990fx sabertooth with a phenom II, and gtx 570. Have the second monitor setup on another desk running another operating system. Want to hookup a dual monitor setup for my first workstation. I'm currently using SoftXpand for my virtual software idk if that matters. The card I want to use is down at the bottom its on sale. I'm not planning on hooking it up in SLI, will this affect my setup or my card performance at all?
