Well, i'm almost decided in buying a brand new powerbook g4 1,67ghz, 15" last rev. i'm gonna use it mainly for photoshop, image editing, and some movie editing. Also, internet, office2004, mail and typical computer use. Does photoshop runs softly in it? I ask this because i saw at photoshoptv (podcast) one guy making a tutorial in his powerbook, and it was low, and buggy... I'm considering buying 1GB of ram too, can someone help wich to choose? crucial powerbook ram There are two types of ram for the powerbook g4 1,67ghz 15". whats the best? these ones: DDR2 PC2-4200 / DDR2-533 or these: DDR PC2700 / DDR333 I'm a little confused, because the first ones, "seem" better, but are cheaper... am i wrong? And the ram that comes with the powerbook its "clocked" at 333mhz, what are the clocks for those ones that i posted? I'm a little worried because, this is my first mac, and i want something good. Thanks in advance PS: sorry for my bad "engrish"
