Thanks for responding Matt. I know AE is more memory intensive. If I can’t max out my computer memory right now, should I get what I can in 4 gig sticks and continue to update as more funds become available. Or should I get 2 gig sticks if I can only afford to get 8 gigs right now. I know I need to get matching pairs. Also what about the 2 512 mb sticks that came with the machine, should I leave them in for now? Or would it be best to match all the pairs?
