So now the new rMBP have been announced, i really cant decide between the following: Base level Haswell 15, 2GHz i7, 8GB memory, 512GB Hard Drive upgrade, for around £1785 OR High end Ivy Bridge (Feb '13) 15, 2.7GHz, 16GB memory, 512GB Hard Drive, 650M dGPU, for around £1650 What's going to be the better option? Will there be much performance difference between the two? I want something as future proof as possible, for music stuff, a light bit of gaming etc. Battery life isnt a huge deal to me, as i'd mostly be using it at home or office really. Will the faster PCIe storage make much difference from day to day? I really can't decide at all. Which is the better machine??
