Install 2 Video Cards on Vista, 1 Nvidia, 1 ATI?

[Cheato3825]

have 2 graphics cards in my computer, one a Nvidia 9600GT which goes to my
22 inch monitor, and an ATI X1550 which goes to a 15 inch monitor. I do this
so i can keep open programs like aim on my small monitor but still be able to
play games on the 22 inch without losing any performance. In XP all i had to
do was install my nvidia drivers and then my ATI drivers and I was good to
go, is there any way to do this in Vista??


I have the latest Drivers, 22 inch acer monitor, 15 inch dell, mobo is a
evga 780i, cpu is core 2 duo E8400, 2 gigs of ram, Vista Ultimate 64 bit

Since the 9600GT supports multi monitor why would you want to use a second
card?

Also using as second card will steal system resources such as your CPU and
memory.
As long as your two two displays are in extended desktop mode you will gain
and not lose performance.

If you want to use Vista WDDM drivers, you can only have 1 driver and all
graphics cards must use that driver.
You can use older XPDM drivers, and then you can mix graphics cards from
different makers.
