I have an XFX Radeon HD 6950 2GB for sale. I will take $190 shipped. I actually have two of these cards crossfired but I'm building a new rig and passing my current system down to my son who has no need for a crossfire setup. The card is a little over two months old and is registered for the lifetime warranty.
