Still trying to decide between the 2,7 and 2,9 Ghz options for the 15" i'm about to order. The 460 is a no-brainer, when you look at the price difference for a 1TB model. I've compared the geek bench results from a different thread to the ones i get for my current mbp (15" 2010 with ntel Core i7-620M @ 2.66 GHz and GeForce GT 330M) and it looks as though i won't be disappointed
My CPU results being
Single-Core Score Multi-Core Score
2315 4477
are almost doubled for single-score (up 190%) and more than tripled in multi-core (up 307%) for the 2,9 Ghz model.
What really gets me excited is the difference in the top of the line discrete graphics you can get in 6 years.
With my geek bench dGPU results being
OpenCL Score
5500
which is way less than a
THIRD of the score the integrated graphics can do

its a change of +348% from my current dGPU to the iGPU in the 2016 model. Comparing it to the dGPU (460) gets really ridiculous. My current dGPU is more than ten times slower than this years model, which scores 57024 in OpenCL, an increase of 1040%
Still on the fence about the processor, but boy, i am not going to be disappointed
