I have a new G5 1.8 single and am new to the Mac world. I currently have 1 gig of RAM in my Mac and want to know if I need to add another 1 gig. I'm primarily going to be using web, email, word, photoshop, imovie, burning DVDs, etc, etc with the G5. Do I need or should I have another gig of memory or would that be overkill? Thanks

you do not need another gig. more RAM is always nice, but really you don't NEED it.

it would be nice though. 2x512MB is pretty cheap nowadays, so go for it.

Well would OS X benefit from the extra 1 gig of ram based on what I am doing or would it just be sitting there never getting any use?

photoshop, imovie, and Safari will benefit from it (especially if you use them all at the same time (safari only after you use it for quite a while though because of it's super-aggressive caching of pages))

It depends on how big your Photoshop files are, and what you plan to do with them. I found that even with 1.5 GB or RAM on my G5, that I'd use up available memory with Photoshop assinged 60% in prefs when I had 2 or 3 50mb files open with lots of history states. I think I have my history states set a either 30 or 50. I went to 2.5 GB of RAM and haven't seen as much swapping. But if you're not working on huge files, or putting them through a ton of revisions between saves, a gig of RAM should be plenty for now. I say use it for a while, and keep an eye on memory usage. If you're spawning 5 or 6 swap files every time you run a memory-intensive program like PS, then you can always add RAM later.

Launch Activity Monitor and check out how much memory your apps eat up. (Check back every now and then during `normal' use, whatever that is for you.) Then add 1/3 of RAM to that and you should be ok for almost anything.

1 gig should be plenty for the average joe or for someone editing `small' images in PS (e. g. from a digicam which are usually around 1 to 3 megs a piece, tops).

Judging from what you tell me, 1 gig should be fine.

BTW, I have 640 MB on my iBook, and I usually multitask between 10 open apps (Mail, Safari, iTunes, Terminal, AdiumX, WordLookup, iView Media Pro (my main library has 13000 pictures in it). It slows down my system, obviously, but it totally within acceptable limits.
