9800XT's Processor is as well faster, as it was on 412MHz opposed to 9800PRO's on 380, plus u can over clock 980oXT with ATI's oen drivers as well, which wasnt available in 9800PRO series.
also, XT was a new chip, RV350 chip for 9800PRO's and RV360 for 9800XT. XT series is still well recomended chipset in ATi's.
