I apologise if such a thread like this already exists, but I wasn't able to find this exact question. If it's been answered please feel free to lock this thread. In any case, I am about to purchase a new MBP. And my decision is between a customised MBPtb 15" base model, but with 460 Radeon and 512GB SSD or the top model. The only difference I can make is that the base model is 2.6GHZ and the totl is 2,7GHZ. The price difference is now 140 euros. Is it worth the 140 euros to spend on an improvement of 0,1ghz?
