They got these results using a card available (new) for $80+ these days http://www.google.com/products?q=9800+GT&scoring=p (8800GT no longer avail, 9800GT uses the same G92 chip).

Apparently, $80 won't buy you even the cheapest new Core 2 Duo, let alone a 1.86 GHz Xeon, which can cost as little as $188 (E5502) or as much as $3157 (L7555) http://www.intc.com/priceList.cfm
