When you have SLI, you get total 4 DVI ports (2 from each card), and say, you have 2 LCDs. Which ports are most desirable to use out of the 4 when you connect the 2 monitors? Both ports from the master card, or one port each from different cards?

forgive my ignorance, since i do not posess an SLI setup. however, i believe i read before that the outputs on the 2nd card are disabled in SLI. wouldn't that necessitate that you connect both monitors to the primary card?

Afaik you can only run one monitor while in SLI mode.

If you run in non-SLI mode, then a single display on each card would be best I think.

I should have been more specific. The 81.85 driver lets you enable/disable SLI on-the-fly, i.e. without reboot. But somewhere along the line I've read that it doesn't work 100% all the time. So the question is more like "When you have 2 video cards (2 ports each) and 2 LCDs, what's the best way to connect them while avoiding conflicts with SLI?"

That's what I think, too.
