how much Ram does 10.4 need to run smooth? i have 512 which i thought was enough. my games seem to run pretty good. but now that im in 10.4 i find it hiccuping lots... when i open dashboard my mac almost comes to a stop for about a min as it loads all my widgets. i dont normaly use a bunch of apps at the same time, but i do use Protools, logic, Photoshop, flash.. DVD studio and final cut. and a bunch of games like C&C zero hour, Starwars KOTOR. do you think adding another 512 would be enough to make everything work more smooth...? i just think the Gig stick might be too much money and i might not use all that ram to justify the price. thanks for your help!!!
