You can use different brands (AMD & nVidia) videocards, and you can also use different models of the same brand (8800GTX & 9600GT). However, if you use two of the same, you have to use the same drivers - like nVidia 172.69. You *cannot* use SLI/Crossfire with different brands, but most people hooking up multiple monitors with multiple videocards shouldn't be thinking about SLI anyway.
trying not to lead the thread away from it's topic, but could you explain this a little more? i tried to install an extra video card so i could run an additional monitor, but i can't set it up >_>

i have a geforce 8600 GT as my original video card, and the other one is a geforce 4000 MX.... the card get's signal from the mobo as the monitor tells me, but i can't figure out how to display anything if you could PM me or reply it would be much appreciated
