Do you honestly think that ATi/AMD would add the extra cost of a 512 bit bus if they thought it would be no better than a 256 bit bus?
Also I seem to remember everyone throwing a hissy fit when the new 8800GTS's and the 3870 had 256 bit memory buses. Why is everyone complaining about this WHEN THEY DONT EVEN KNOW HOW MUCH THE CARD COSTS TO THE CONSUMER?!?!?!?!
It's very naive and ignorant to make any assumptions on this card based on the few facts available and expecially without a retail price.
We already know the MSRP for the HD4870 is $350ish. I don't know anyone who was throwing a hissy fit when the G92 and RV670xt didn't have 512bit interfaces. The H2900xt has the same performance as the HD3870, but costs twice as much, that's why I think the 512bit interface is a waste of money. It's been proven to take up a :turd: load of power and doesn't give extra bandwidth. The HD4870 has a more powerful core, but that is countered by GDDR5's insane speed. It'd be the 2900xt all over again.

RV770 has been in production for a few months now. They've had 71% yields, this 512bit interface is a rumor until ATI tells everyone they messed up, again. The 2900xt was a terrible card for it's price. It used too much power, was too expensive, and didn't perform for the amount you paid.
