According to this guy

the 8800 Ultra is better than the Gtx+. I havent found one on a retail site (Like Amazon or Newegg) But theres a few people selling them on ebay. The bids as of this post are 53$ for both, but they have 10 hour difference in ending times, and shipping is 10 and 7.50 respectively. Course, tomarrows the last day for these offers, so im not sure how helpful they are.

Anyways, here are the Ebay links

Good Luck in your Search.

EDIT: wait, its PCi, not Pci-e? All the links i have are Pci-e...
If it Is Pci, then you might be better off getting a new computer, due to the fact that pci is
really outdated. How did you find out it was pci?
