1 days old (11th June). Haven't used (haven't installed OS) but already plug into PCI slot. Not compatible with my research OS. Total 2 sets. Retailing for $265 brand new. I'm selling at $240. My loss, your gain. Oh $240 for each. Don't be a sucka now. Cheers peeps! P.S: There's no room for negotiation. So I don't expect lowballers at the table.
