I have for sale a GTX 580 Hydro Copper 2 1.5GB. It has been used for almost a year and is in superb condition. I am starting to part out my computer because I am in need of cash for bills. Has 1/2 inch barbs fitted and will also come with the 3/8 inch barbs. Will also come with original box, documentation, and some wires (some might be missing but nothing essential). Need to sell fast so I will be moving to eBay if no interest in a couple days. Asking $300 shipped.
