I'll be upgrading my ram and hard drive in my 2.16GHz Core 2 Duo Macbook (last gen). 2GB x 2 ram. Figured it would be easier to just chuck in two if the same strip then to figure out where to put the 2GB strip. The hard drive I have on order is: 200GB 2.5" Seagate Momentus 7200RPM SATA Notebook drive with 16MB Cache & G-Shock Protection (SEAST9200420ASG) I should have them in a week or two, waiting for the PO to be processed. Should I notice a large performance gain with this? I notice my MB w/ @GB ram seems laggy at times. Hoping to get extra boost out of it.
