This machine is already very powerful at it's' base config and price of $2199. But I am curious what you guys think is the best value among the BTO options? Starting w/ the base model, I would upgrade to the 2.7GHz i7 and 16GB RAM. The RAM upgrade is the easiest choice, as it is the one option that cannot be compensated for after built. And only looking at benchmarks, the $100 upgrade in processor was easier to swallow than the $450 option, since the performance benefit seemed to start to plateau. For storage, I just didn't see the GB/$ value in upgrading to 256GB for $350. With so many alternate options here (like external storage and cloud storage) this deficiency can be solved.
