I want to take the plunge to run XP on my Mac Pro 2.66 Dual Core with 1GB RAM. I plan to use Quicken, Garmin GPS software, maybe games, and miscellaneous non-intensive Windoze-only things for work. I have not bought the OS yet. My question is, should I get Home or Pro edition? What are the main advantages of Pro over Home edition? Does the fact that "scalable processor support" is only with Pro mean that >1 processor is wasted on Home? I plan to buy an OEM version. Any recs on good sources? Thanks.
