In any case, if those base specs are too weak for you, you can get it with an i5 or i7 processor, 8GB of RAM and discrete NVIDIAGeForceGT 630M graphics with 2GB of memory.
The MacBook Pro with Retina display features the latest Intel Core i7 quad-core processors up to 2.7 GHz with Turbo Boost speeds up to 3.7 GHz, NVIDIAGeForceGT 650M discrete graphics, up to 16GB of faster 1600 MHz RAM and flash storage up to 768GB.
There's a bit of a surprise inside the expansion dock: by laying the M2432 on top of it, not only are you adding six extra USB 2.0 ports plus DVI-out and another HDMI-out, but you're also kicking up its graphics power with the built-in desktop-class NVIDIAGeForceGT 440 with 1GB video RAM.
