the 88gt i had was very finicky about what sockets it supports. it just wont run on a 1.0a pci-e slot on non nforce motherboards.
i had a asus board that had a via chipset at the time, but had to buy a gigabyte board with an nforce 450 chipset and socket 1.1 to get the 88gt to work.
so you better check with the manufacturer via email, to see if the card will work. they should be willing to help. if they have any kind of decent customer service.
