About $65.
You know he's talking about the G80 8800GTS right? The expensive kind that performs worse than the G92 cards and is becoming obsolete.
I'd say $120 should be your minimum price. Here in Canada, they are still being sold new for close to $400. I actually just bought a used pair of them for $300 which is a great deal considering I paid $500 for the one in my sig when I first built my PC...
You know NCIX.com has prices pretty much equal to newegg... those should be no more than $130.
