But they're not the same price, thus not direct competition. Sure, 9800 benches would be nice, but a 9800 Pro is meant to compete with a 5900, as they're both $400 (vs. the $300 9800).
I'd like to see a board comparison like GamePC's reviews, too, to see how the high-end stacks up to the mid-range.
BTW, if you want 9800 numbers, check into some of FiringSquad's latest reviews.
