So after upgrading my system I have been selling off most of my 780/6gb cards. I already sold 3 of them to another Octane user here but have another for sale now.

All in perfect working order, comes in original boxe with documentation.
£250, payment via paypal (confirmed address's please!) would prefer UK buyer but can ship internationally at buyer expense. PM if interested.
