All cards right now should be the reference design; aka with volterra chip. I think what XFX is doing is sort of "promising" the potential since they can't exceed the 300w tdp limit of whatever industry standard it is called. PCI-E 2.0 spec I think. Therefore you SHOULDN'T see any cards with a large factory overclock in the 5970's. Only 6w to play with before hitting the limit.
