Exactly this!I dont think it is worth, both have 4gb vRAM now...and when i test my workflow the 2.6 ghz i7+560X was always 10 celsius above the current 2.2 ghzi7+555X
This should matter if you keep your mac for 2-3 years
I went for the prebuilt model with the 512 and 560 for a couple of reasons. The slightly higher clock CPU clock speed and most importantly the ability to get a replacement machine at any Apple store. If my machine dies on travel it can cost me hundreds per hour of billing. I want to be able to be able to pickup a replacement machine with the same configuration at any Apple Store.For a causual user (non-gamer) is the 560x worth the upgrade over the 555x? Particularly if you plan to keep the laptop for 5 years or so?
Otherwise plan on ordering the base model with 512GB SSD upgrade. Thanks.
