worth a DX11 card?

[Flyby]

oh, btw, if you follow the link to hardwarecanucks' review of the 2gb ATI 5870 jump straight to the conclusion for the bottom line on performance. SPOILER ALERT!!!!!

There is not much benefit to just adding another gig of memory to this card. That seems to be the essential truth of other reviews I've read of video cards that added that extra gig of memory. If nothing else in the architecture changes, then the results are minor at best. Now if the memory bus was opened to 348mb or 512mb we might see that extra memory put to good use, otherwise it seems a bit of a gimmick. I was hoping this time it would be different. Maybe it will be different in SoW, at least to possibly limit stutters.
