Decided to go for 16GB RAM what ever happens. It's just choosing the best processor. Obviously looking for best bang for buck with an essence of longevity. Main uses are Web browsing YouTube iPhoto and Lightroom Netflix Some doc editing. Processors I'm torn between are as follows 2.8GHz Dual-core Intel Core i5, Turbo Boost up to 3.3GHz Or 3.0GHz Dual-core Intel Core i7, Turbo Boost up to 3.5GHz Any suggestions would be appreciated.
