the fact the 9800 has twice the pixelpipelines and a 256bit bus means the 9800 will obliterate the 9550, clock speeds arent evry thing ya know.

well thats may not be full pro, as the pro did have originaly a 256bit bus , but still the the 9800 core is superior to the 9550 so the clocks speeds shouldnt matter too much.
means it can process 8 pixels per clock were the 9550 can only process 4 per a clock
