Hi, I need to upgrade my MacBook 5,1 2GHz that currently has 1x2Gb RAM and 160Gb HDD. I do not really need to make it right now but I wonder if prices will change a lot in 5 months time. I either do it now, or in the end of August. What do you guys think? The price of 2x4Gb RAM will change a lot over thar period? And the HDD, 500Gb, 750Gb or 1TB, will it have a big drop in price? Hope someone can give me some prespective on this. Thanks a lot.
