i'm upgrading my ram (from 128 to 640). i haven't done it yet since buying my computer in august because right after i got it, the price of ram kind of shot up and i haven't been able to mentally justify paying 20 more dollars than i originally planned to. but i think that i'm going to do it anyway without waiting (os x is too slow to wait so long). so, those of you who have had this or a similar experience, tell me how it really helps. most of the time it gets slow, it's the hard drive that's spinning wildly, not really a problem with the RAM - or is that virtual memory? i can't really tell. i don't see how just running the finder and classic mode with no other programs running can cause such hold-ups sometimes. also, is there a way to make ram disk in OS X? used to like to do that in classic OS's to "optimize" a game or other program. i'd preferably like to do it without additional software evern going into the terminal(??? maybe???) but third-party is fine. any ideas? thanks.
