The fact the there will be no DDr II dimms available, due to no JEDEC standards, has absolutely nothing to do with videocards, as they only use the raw chips with their own controllers..... I'm fairly certain that both nVidia & ATI already have their hands on said chips...... Samsung said they had already produced DDr II chips in May, and Micron said same in July.....
