Currently my powermac g5 dual 1.8 has 1GB RAM. When using it, everything feels pretty snappy, only some programs take a while to load(xcode, photoshop etc). Even when I have a few heavy duty programs open(safari, itunes, photoshop,xcode, interface builder, adium +more) my computer handles them all good and there is no lag. Do you think i should buy 2 more gigs of ram for my computer. It would cost me 90$ CAD. That would bring my total up to 3GB. Or should I buy 1 more GB(2 x512)? I have the model with 4 ram slots, and 2 of them are already used up. So what do you think? Should I buy 2 more gigs (90$), 1 gig(50$), or just buy nothing and keep it at 1GB stock. Btw im going to be using this computer for as long as it lasts, so hopefully 3+ more years. Its mainly used for xcode, safari, itunes, and photoshop. Thanks.
