I've read that having huge amounts of ram like 2-4 gig can actually slow down your computer in general use.
2gig is good if you do rendering and for some games (if you have quality ram), but apparently you get a performance hit at other times.
Don't quote me, it's all heresay.
I'm not sure having 4 gig would be of any great benefit unless it was of the quality, low latency, dual channel variety. Probably for most applications, not even then. And that would be expensive.
I wonder if the performance problems some people are experiencing with FPSC is because of small/crappy ram?
I have 1gig of geil ram and apart from some loading slowdowns on Battle For Middle Earth it never skips a beat.
Also, for the record, dual core systems can also be slower for some apps, especially if they're not made for dual core/hyperthreading. But that's being picky.
