Multiple Video Cards in same computer question

My 6800GT only has one DVI out and it's used by my projector. I can't wait any longer and want to buy an LCD monitor but must hook it up with DVI or I'll lose sharpness.

I'm going to have to add another video card. I have tons of experience with multiple monitors but none with multiple video cards. I want to eventually do something like this:

or this:

or even better for comic scan reading:

omg, this would have rocked beyond belief for daytrading:

I've seen plenty of examples on another website of multiple video card setups but can't find this answer. Which video driver handles the task of cofiguring the two monitors? Can I use multiple video cards and still configure them to be one big monitor like I do now? I still want to be able to drag things back and forth from my new LCD to my projector screen. Anyone use two video cards with XP?

I'm planning on accumulating 21.3" Samsung LCDs.

Ahhhh grasshoppa...

Windows is smart... two graphics cards, two graphics drivers... one is primary, the rest can be extended desktop... you'll have no problems using the desktop control panel to configure all monitors.

Nice : )

Problem is, I need to buy a PCI card as there's only one AGP slot. I may get a dual DVI 6800GT for 200.00 but then I'd have my 6800GT sitting there with the best performance but unusable. I guess I need to see if there's a dual DVI PCI 6600GT out there. All I really need is good video performance for my projector as I tend to play games on the CRT (soon to be LCD)

You will need to go into the BIOS on your system and set which video card is to be the primary. Basically you tell it to boot to your AGP card, then windows will take over and hanle all the multi monitor stuff.
