Well, my 17" MacBook Pro lasted just about three years being used extensively the whole time. It replaced Windows and my Dell Dimension desktop computer. Now I'm having problems with freezing frequently enough to figure I should just get a new one and make this my backup computer. In any event, I'm going to buy a new 17" MacBook Pro and I'd like to know if the following link/memory would work as an upgrade: http://www.newegg.com/Product/Product.aspx?Item=N82E16820349034 I'm intending on buying two to bring my notebook up to 8 gigabytes of ram. The one I intend to buy in a couple of hours is 4 gigs.. Let me know what you think.. Or if you have a recommendation for something better, please let me know.. Thank you!
