Hi, I'm getting a second hand Macbook Pro 5,5 from a friend who recently upgraded her Mac. I'm new to using Macs so any help would be appreciated. The Macbook Pro 5,5 is in good condition but it was recommended that the RAM and Hard Drive be upgraded. Would anyone be able to offer me tips on what kind of Hard Drive to get? I think the maximum size is 1 TB but I wasn't sure if it's better go get a 1 TB 2.5" Hard Drive at 5400 RPM or a 750 GB 2.5" Hard Drive at 7200 RPM. Does anyone have any thoughts on that? I'm not sure if the speed of the RPM makes that much of a difference? Also, from what I understand, the max capacity for the RAM is 8 GB so I am going to purchase this: http://www.amazon.com/Kingston-Tech...6K2-8G/dp/B001PS9UKW/ref=cm_cr_pr_product_top Any thoughts on this?
