Second video card for displays/folding

[zoob]

Hi guys,

I'm looking for advice for a second video card for the following (in order of preference).
- Stock single slot passive cooling, or accepts an Accelero S1
- Drive two LCD monitors through DVI (1600x1200, rotated 90 degrees)
- Decent PPD for F@H
- Dual-link DVI support

Prefer nVidia as I have a GTX285 for my main video card. Any suggestions? I was thinking of getting an 8800GS. I also run Windows 7 so if anyone has experience running nVidia+ATI in the same rig that may also work... in which case I'd just go for a cruddy 3450 :)
