So glad that I stuck with my 5970 instead of jumping to this minor generation update. It doesn't introduce a new level of OGL/D3d APIs, nor does it shrink the process size! Completely useless imho.
People looking for a good card to run on r600g should try to find a HD5870 or 5970 -- the support for evergreen is really in a much more sane state than Cayman / NI. Six months from now they may be on par, but six months is an eternity for people who upgrade their graphics card every 2 - 3 years.
