I've posted a thread regarding difficulties I'm having with a faulty previous generation MacBook Pro 2.66, to the point where I've wondered if a laptop is a good idea at all. But that is a separate thread, and keeping the laptop options open, I'm interested to know, will I notice much difference between the: previous generation MacBook Pro 2.66, 4gb RAM, 6mb L2 cache, 512 discrete graphics and the previous generation MacBook Pro 2.4, 4gb RAM (could self upgrade), 3mb L2 cache, 256 discrete graphics (appreciate hard drive is smaller) The most strenuous task this will regularly face is running several Adobe CS and MS office applications at the same time. Realistically, how much extra (cost wise) is the 2.66 worth? Will I notice much difference in performance for the above tasks? My other thread asked for comparisons between the maxed out Mini (but with 2.0ghz processor) and the 2.66 MBP. How would you guys compare the maxed out Mini with the 2.4 MBP? The easier upgradeability of the MBP is one plus.
