The one I have looks just like the one in the pic. It's visiontek. I would say it will not fit the original stock heatsink. They may have a stock style heatsink designed to fit the v2 boards but its doubtful. I don't see what purpose they would have for doing that. Hard to say what's involved though, I don't see why they would change the original design in the first place. Anyone want to buy a 5870? It stays under a breezy 100c...
