Hmm i dont see this as a dissapointment. I wouldnt want to be playing new games at 16x12 with this card anyway. More like 12x10.
Plus I think its pretty good that A) it OCes to 490~ on the core and 1300~ on the mem, B) You get many features that the X80XT is missing (S.M 3.0, pure video, HDR, etc) C) Its going to get cheaper as it looks like the demand isnt that big (as seen by the threads response to the card), D) low power, heat E) I would get this over a X850XT because MOST big name brands like EVGA has it factory OCed to 460mhz on core which clearly would beat the X850XT PE. F) Get this card if your going to play doom3 engine based games e.g prey, QW ET.
That is pretty much my take on it.
