Got this wrong. A PC100 DIMM is 64 bits wide, so theoretically you could
get 8 bytes/clock cycle off it for 800Mbyte/sec bandwidth. I still think
267Mbyte/sec is a hefty chunk of that. And a lot of people run at higher
than 1024x768, at higher refresh than 85Hz.
Of course people who can afford a monitor that can do that kind of
resolution wont be caught with an i810 main board..
