Well I think you should use Voodoo 2 2000 as it is the best solution for pci products.
But it is a quite old card and it cannot run latest games quite fastly.(well i don`t know if it does not run

).Well new cards are available in pci mode in which some are:
Geforce 2 GTS pci
Geforce 2 MX pci
They are available at low cost and Provide Reasonable Performence.
I think it will solve ur problem.If you have any other question just mail me at

Other wise visit anandtech vedeo section and here is a comperison of tntm64 and voodoo 2 2000
and voodoo 2 SLI
