Extrapolating from this review:

It pretty much has the same core as the GTX 275, only clocked slightly higher, and the four missing ROPs and gimped memory bus aren't that critical to the performance of the card. I think the price premium comes from it being a flagship part, and nothing more. NVIDIA pretty much cannibalized the GTX 285 by releasing the GTX 275 in it's attempt to stay competitive with DAMMIT's 4890.
