Will they make a direct x10 video card fot the old PCI slot?

I'm talking old skool PCI slot....I have workstation that I use with my company, an older computer that still works really well.....I'm gonna hafta get some new graphic rendering software that is only compatible with Direct x 10 and vista....I know my computer can run vista, but will they make a direct x 10 video card for the old school PCI slot as my workstation motherboard doesn't have AGP or PCI-E???|||Probably not. You will most likely have to upgrade to a PCI-e card.
