If you suffer from small wallet syndrome, you may want to consider a Voodoo 3 3000 PCI on sale at Bestbuy for $99.95 with a $30 mail in rebate from 3dfx. If you have a little more cash on hand, I would consider a Geforce 2 MX for a little over $100 or so. From the reviews I have read it sounds like the Guillemot Prophet MX is the best one, but it goes for $150 retail and between $130 and $140 on the net.
