im betting this was done as a rush job, get a dx11 great chip out asap to get some market share. then i think once nvidia gets their monster chip out, ati will be ready with an even bigger one after the 40nm process is spot on. i think were either looking at the 5830 equivalent, or it will actually be the 5870, and we will see a 6870 very early 2010.

lets all hope this one can clock above 1ghz stock, and OC 20+% more, or there may be no need to jump after it if you already have a 4890. but the pricepoint seems to be well within the range of anyones budget
