can you mix and match pci-e gfx cards for multi monitor setup ?

[Things change I've changed]

I've had a very hard time looking for information on this topic and am hoping someone on here can enlighten me, my next motherbaord is the intel Desktop Board D975XBX that has 3 pci-e slots, I need to have 3 monitors running off this board, can I put a 7900gtx pci-e in one slot to power 2 screens and then purchase say a cheap 6200 pci-e and run another monitor from that, OR, would I have to match the 7900gtx meaning I would have to buy another one just to run an extra screen ? any help would be greatly appreciated.

You can mix and match but I'd stay with one manufacturer (Nvidia/ATI) just for simplicity and compatibility

On this subject, what about having a low power card for everyday use in 1 of the slots ?

I'm thinking I don't need my X1900XT firing all the time, especially if I just boot to check emails etc. quickly.....so, any ideas on how to disable the XT for some boots and the 'cheapo' for others ?

I'm thinking BIOS may provide, or perhaps hardware profile in Windows ?
