Multiple graphics cards/multiple monitors
For some time now, I've been working with a 3 monitor setup. (I do a lot of graphics work.) I use a dual display card (geforce 6600 GT) to drive my main central monitor, and the monitor on the right.
I use a second cheap card (geforce 4 mx 4000) in the PCI slot to drive the left monitor. So far so good.
But I'm getting ready to build a new system, and now all the rules have changed. Apparently everything is PCIe now, so I'm wondering how I'll be able to do the same thing.
I'm figuring that my new main card will go in one of the PCIe x16 slots. So will putting a second, cheaper graphics card in the other x16 slot allow me to extend my desktop onto a third monitor? Or are these slots only meant to be used in conjunction with SLI/Crossfire?
And what are those smaller, PCIe X1 slots for?
And speaking of SLI/Crossfire, is that something that's only supported by specific games?
