>how much bandwidth does the GPU need for normal, mostly static 2d stuff?< An ISA slot operating at 8 MHz should be more than adequate for most 2D stuff. I would guess that typically, the bandwidth would be less than that of a 56K modem.

>If the GPU isn't rendering dynamically, and the monitor is just being refreshed out of a frame buffer, there ought to be plenty of bandwidth for the cpu to "steal".< The question is, where does the frame buffer reside? Presumably, with the nForce chipset, the default is for the frame buffer to reside in main memory. Thus, the frame buffer could eat up a lot of bandwidth. However, even in this case I would anticipate no more than a quarter of the bandwidth of a single 64-bit DDR DRAM channel would be used.
