(i accidently posted this in the macbook pro section, but the answer still applies) Hey everyone. Sorry if this is a repost, but i was looking at ram OWC on here:http://eshop.macsales.com/shop/memory/Apple_MacBook_MacBook_Pro/Upgrade/DDR3 and my question is why does the price of ram jump from 4gb at $64.99 and then 6gb is $374.99. That is a pretty big price jump for 2 more GB. Can anyone explain to me why? Also i have 2Gb of memory and how will adding the 2 more GB help my computer? will apps be snappier and of course i would have more memory. thanks!
