Offering two identical and completely practical N570GTX Twin Frozr III Power Edition/OC cards. It includes the SLi cable visualized. There is zero fan knocking or coil whine. These bad kids served me well however I've updated and they require an excellent home. These were never overclocked or overvolted throughout my use as I felt they were plenty effective, but the overvolt function does work unbelievably well on both if that is something you are interested in. Both can be found in anti-static bags in MSI provided boxes. They are being sold as a pair and include the pictured SLi cable. , if you have any concerns don't be reluctant to ask me.. All sales are final.
