ok, so that seems like an obvious yes answer. but i would like to know what kind of gains i should expect. i mainly use my mini for web surfing and paper writing right now. but this summer when im not in school i plan on taking many trips with my digital rebel, and doing photo editing, etc. also, being forced into using 1 monitor is driving me crazy. im curious about the powermac 1.6ghz's performance vs the 1.8, an the newer ones, upgradeability, and i also have found that i can get one for about 1100$ in really nice shape. would it be worth it to get the 1.6 powermac, and then sell off my mini?
