I, for one, am not even remotely suprised by these results.
For one, the FX series cards aren't worth the metals used to make them. In running tests on games, the FX series of cards consistently are at the bottom of the rungs in terms of performance in the field of T&L cards, and are generally pretty poor at rendering anything with shaders.
For another, graphics are rarely held back, in the ranges of cards we're discussing here, by the processor. On most current games, even if you have a 1.5gig processor, you will still see FPS increases by upgrading from a 9800Pro to a X800Pro. Granted, a jump of 1ghz in processing power may show a greater increase, but the difference is still there, and still tangible.
