After reading the Spanish review, I got a better impression than with TPU... Also, I dont think we can rely too much on %.. If we were talking about low FPS, sure.. but talking about FPS in excess of say 80 FPS, 15-20% is really a high difference, like 16+ FPS which is quite good for something which uses the same chip, with little changes.. If GTX480 have been this, the feedback nVIDIA had would be a LOT different!
