They won't support a v3 1000 as it's an OEM card, but the 2000 drivers should work for you, they work for my friend. It's basically a V3 2000 underclocked to 125 mhz. Try getting older drivers first, as the newer ones might have some utility that doesn't allow installing of the drivers. (3dfx isn't supposed to support those cards which is why crappy OEM's such as Compaq put them in. )
