Just got the new 15'' MacBook with a 2,7 processor and 455 graphic card. It's running Logic Pro X extremely slow. The lag is unbearable and it starts to crap out when I'm only 10 channels deep in to a project, final product usually ends up at 60+ channels. Logic uses 120% of the processor power to run only two plug-ins at the same time (NI Battery and stock Multimeter). Meanwhile, my 5 year old iMac is running logic smooth as butter. Am I missing something here?
