I am looking at a new computer just for running a 4 axis cnc machine using a smooth stepper. Does the speed of the processor effect how Mach3 will preform? I understand it will run on 1Ghz, but will it run better on 3.3GHz. Does it matter if it is a duo or quad processor? What about ram,would 4GB or 8GB be better than 2GB? I will be use Windows7. How about the video card,512,any suggestions? I want to make sure I can get the most out of Mach and my machine without going overboard. I am very new at this so if has been answered before just point me in the wright direction. Thanks,Tommy
