I have an older VIA EPIA M1000 in a bar-top machine, which I think is 1ghz; works well enough running the "classics" using MicroXP and an older version of Mame - can't quite remember what version I am running; maybe .87 or so? The main issue for me is the audio. I had to set Mame to run audio at 22khz to avoid serious audio stuttering. Since yours is a newer motherboard, the on-board audio might be improved, and the faster processor should help things as well. Don't expect to run any of the newer, more complicated games however. But should work fine for a majority of the classic arcade games with an older version of Mame.
