No.
You try and sell on eBay and you might get a chargeback due to Paypal protection.
You try and sell it locally like that and who knows... might get robbed or might get into some low-balling people who just waste your time...
No idea why you would even sell at a time like this since by selling you would lose more money than selling it at a huge markup right now.
Charge back for what?
The buyer has a %100 feed back.
I have been on ebay since 2000 and only had one issue and that was as a buyer.
I already made my ROI months ago and with the new cards coming out I wanted to sell them while I could get top dollar.
I made money by selling them and when you consider when new cards, AMD and Nvidia, come out in the next month or three the prices on used ones will drop and the more they drop the more my profit will end up being.
