um they start @ about $100 for a New OEM one, or a retail one (like $110) and is ita 128mb or 256mb one? if you have all the papers and the box and the software it came with, and it's in good condition. i'd say $60-$70 maybe. it depends on how much ram it has and which company made it, like if it's made by ATI then it would be worth more. or if it was made by HT (high tech)
