I'm just also going to throw this out there for what its worth...
My computer running my bot is older. AMD Athlon X2 Dual Core Processor 4600+ 986MHz. Ram is just under 2 gigs. Running SB3 on Windows Media Center Edition 2002. I don't connect it to the internet. And I don't have any programs on it other than Cabinet Parts Pro, PartWorks 3.5, and Partworks 3D. All of which are closed when running parts.
