I'll soon be purchasing XP for my new build. The Home edition has served me well the last several years, but now I'm wondering if XP Professional is worth the extra $50. Is there a performance increase, or simply additional support for esoteric networking protocols and such that I probably won't use? I plan to game, use Dreamweaver and Photoshop, encode some video, and use professional audio software like Cubase and Wavelab. I use a wireless ethernet adapter but am otherwise not on a network. Any good reason to go with the professional edition? Thanks..
