Perhaps, but it was with some sort of liquid nitrogen cooling system... and it was 3D mark 05, not 06 (Which chews up videocards and spits em back out with a 500 point rating).
I'll wait to see an article on "2900XT goes on massive sale", or "2900XT latest drivers deliver 100% performance increase, edges out GTX in at least two games for less, no overclocking!"
Sadly, the XT, for me, is a bit far away, both in cash, fitting in my case, and time... (Although, Futureshop is stocking them now), so far in fact that I might just wait for the next "refresh" of the cards in 65nm. So I don't have to buy a new PSU.
