GEEZ! FINALLY!!! I am an ATI fan, and I had ATI cards all my life. It's only been recently that I got in to nVidia since I just bought a laptop. And apparently, based on very extensive reasearch, only nVidia mobile GPUs seem to have GDDR RAM.
I don't know if ATI's support for Mobile GPUs is worse or better. Needless to say, I got very impatient waiting for nVidia to release updated drivers for my notebook.
Shopped at Newegg.
