bleh.. It's good from the standpoint that ATi could theoretically get a nice boost from this in the consumer line, but I doubt we'll see much help!
after all, if ATi DID move to the 256bit memory bus, that would mean they wouldn't have to worry about memory limitations nearly as much, and could simply continue with the setup they have right now (ie, HyperZ etc).
BTW, congradulations LXi, and Noriaki on attaining Elite Member status, it is well deserved!
