I had an old HP desktop (DC5750 2.1GHz) lying around so I thought it'd be perfect for my LinuxCNC project (converting an RF30 to CNC) but its jitter seems to be around 94kns if I really move the windows around fast, otherwise around 55kns. It has 8G of memory, a dedicated video card (granted with only 256MB). I was a bit surprised since it seems to work/act pretty decent. I guess the question is, is the PC really unusable or can I tweak some settings (or plop in an old 60G SSD etc) that would improve the latency?

I've tried a couple of HP machines and didn't have much luck with them. The ones I tried had very limited control of bios settings, and I could not turn off power saving features to improve latency scores.
