Um guys, this is supposed to be a "Pro" remember?
"which means After Effects users, 3D users etc will be better served by the PC platform unfortunately. "
Unfortunately? This is how it has always been. Macs are very famous with their crashes during heavy 3D rendering or AE comp. pre-render. Sorry to tell you this but PCs have always been more stable when pushed to the limits of the machine.
The reason I hate Apple is not that I am a PC fanboy or I can't afford it. The reason is Macs costed me projects, they costed me time, and they costed me salaries. They crash and trash project files, have poor reliability, poor compatibility, poor upgrade-ability, poor price-performance and last but not least - poor navigation in the OS.
P.S And if somebody starts crying "I was using windows and it crashed, and it ..." Well stop comparing office PCs for 500 euro with Macs for 1500. At the same specs PCs have always been more stable. At the same price you get even a bonus - performance.
