My experience with the AMD II-X4 machine from Wally world is identical to Brett. I ran 192000 with 256 and the rest at 128 and I NEVER ONCE heard a glitch with VAC running WDM-KS, 8000, 512 and any of JT65-HF, FlDigi, MMTTY, MMSSTV along with logging programs DXlab with spot collector, dxview, etc. I used VSPmgr and Eltima serial cables.
I used N1MM with keying during the Stew Perry and it never blinked. Near QSK, etc. I hope the quality of the parts holds up in the machine because it is a fantastic performer. Its only "lack" is VGA connector Nvidia video. The Windows "experience" is 3.7 and this is completely dominated by graphics performance. I keep my display update to 10, but I could run it higher if I thought it bought anything. I never once even started GBoost. There was no need. So, I am very pleasantly surprised, especially after getting a refurbed earlier model for more money from Tigerdirect and having it arrive DOA. I think this is the thing that drives me personally to scratch my head until I have at most three hairs left on top. I cannot explain why this inexpensive machine performs the best of anything I've plopped down in front of, but I will take it.
