Hey, i know this has probably been asked like a million times, and i have searched the forums, but have not found a definitive answer! I have a 1.33Ghz iBook with 512Mb ram.. And according to some threads, the large pageouts on your Acivity Monitor is not that great. I currently have like 925845/328657 pgins/pgouts. And each time ive only got about 5 to 8Mb free RAM left. So i was thinking, the OS runs fine as it is, but it is times when i load iPhoto that it lags a lot. Plus, i don't think im the average iBook user. I usually have Word, Excel, iTunes, Safari, Flash, Azureues, Limewire, System Prefs, Messenger, Quicktime, all open at the same time. Sometimes i open up Photoshop as well. So occasionally things beachball for a bit before returning to a normal pace. So my question is will upping my RAM help to smoothen the operation of everything since i have that many apps at once? And how much? The difference is that its only £40 for extra 512Mb from Crucial, and £100 for the 1Gb if i wanna max it out.
