It is not long, when ATi made show that their top level card know how to adress 1 Gb of memory. Now Nvidia announced, that Their cards based on chips G70 and NV40 or NV45 can adress unbelievable 2 GB of memory. It is more than most people have in their pc, so usability of this is questionable, but sure it is good for marketing.
