Hi, I'm new to the world of mac having just purchased a dual 2.3 2gb powermac running the latest Tiger os. I know these mac's are fast, very fast, but have notice some wierd things. Let me explain.... I was running some tests with a image of 200mb plus, mulitple layered, 2000x2000 resolution image in photoshop and then guassian blur with no slowdown or problems, its what I expected to be honest. Now, if you open your widget panel (f12) and continually press a widget icon, the machine really struggle to keep up. Its dosn't seem any where as graphic intensive as the photoshop test but it does struggle. Unless its just my machine. Chev.
