I'm looking for some advice.  The PC I've been using to run Mach3 and my mill has died an I want to build a new one.  I'm not current with today's computers.  The one that died I built 10 years ago.

Does anyone have a good 'shopping list' to build a dedicated PC for Mach3?

The pc dosen't need to be the greatest , as compared to just a few years ago costs are low,  and you can get a lot for your money these days. It's hard say that  some pc will not be problematic. A few years ago i took a different approach and had one built ( cost about
$60 extra as compared if I had done it myself....but......the local company guarenteed it to work to my satisfaction for CNC work or they would replace or change out any component of it until it worked. If the component cost more then i would pay the difference in price. Can't beat that!
This is the basic components that mine has:
- Asus motherboard - M2N68-AM SE2
- 2 GIG Ram
- AMD  64X2 Dual Core Processor 5200+ 2.7 Ghz
- Asus graphics Card - EN9600GSO
- Rosewill PCI pp card - RC302

The PPS in the driver test will only change by 1 at 25khz. No changes were required and note that i didn't buy the best of components.

I am happy with it but really can't say you would be,
