Price: Up to $800, lower is, of course, better.
Performance desired: Higher performance than a single 8800 GTX
Monitor Resolution: 1920x1200
Rest of system, while I'm still deciding on a few things, will be: q9450, 8GB ddr2, choice of GPU will determine mobo, rest I don't think has bearing?
I really don't want to need to disable SLI every time I want to use a second display.
