I'd bet that the video card is to blame. If not make sure that you are
using nvidia (and not nv) for your graphics driver, and that
/proc/drivers/nvidia/agp/status shows that your running the correct AGP
rate. One of my friends tried to build a system on a motherboard with
built-in graphics and he had the same stuttering problem. I just purchased
a GeForce 6200 LE from Circuit City about three months ago and it works
great @ 1080P. Its passive heatsink is much quieter than the old 5700
Ultra's I was using before.
