I have one pci-e x16 slot and one pci-e x1 slot. I am running a Galaxy 512mb 9600GT in the x16 slot. The primary monitor will be connected to that. I understand that the just the first card renders the graphics. Does this mean that it doesn't matter what kind of card I get for the pci-e x1 slot to run the secondary monitors?
XP will support different GPU's with different drivers, although a lot of folks say it's kind of a pain to get it work correctly. Never tried it myself, just going by hear-say.
Vista will support more than 1 card only if they both use the exact same drivers.
I actually just meant, will it matter if the card I put in the pci-e x1 slot is older? I have just heard that you can have a cheapy in the 2nd slot and it wont affect graphics that much because the first card renders. Is this true?
