Need help buying a machine to run GS3. I am considering a Gateway machine with the AMD 4200+ and SATA II HD, 2 GB RAM. Would this setup work? I read that the Intel core 2 duo chips are not stable. Is this true?Also, could someone expand on the SATA II spec? I am a liitle confused about some of the problems people are having with GS3. At $129, I would like to get GS3 up and running.
