$110 shipped should be right on the money. Considering a G92 GTS goes for average 100 shipped, and outperforms the 8800 GTX, i would say its not in performance view worth 10 more bucks, but worth the extra 10 bucks because its a piece of video card history IMO.. That used to be the baddest boy around until the ultra came up. There not to common anymore either, and its still a great card.
If you check ebay though, you could prolly get it gone for around 130ish..
