[ale] Nvidia Magic for dual head

[James P. Kinney III]

I concur.

1024x768x24bitx30frames per second= 566,231,040 bits per second
through-put on the graphics subsystem. Using 8-bit words, that is 70MHz
clock (70.77 MHZ).

Assuming a 320x240 frame at 8 bit color, and using an 8 bit word
transfer chunk, the clock would have to be a whopping 768 MHz! 

I don't think even SGI has that kind of graphics bandwidth.

At this point, I suspect that the error here is in the units. I wonder
if fps is really tps (triangle per second). 10k tps is actually a
realistic number for a graphics card that costs under $2k.
