Apple Mac Pro Intel Xeon E5 16GB 256GB OS X Mavericks 10.9

Mac Pro is the professional desktop computer reinvented from the inside out. Arranging the most advanced technologies available around a unified thermal core allowed to make this the most powerful and expandable Mac ever, yet also unbelievably compact and quiet. Mac Pro comes standard with dual AMD FirePro workstation-class GPUs, each with up to 6 GB of dedicated VRAM and 2048 stream processors, providing up to 264 GB/s of memory bandwidth and up to 3.5 teraflops. That's enough power to edit full-resolution 4K video while simultaneously rendering effects in the background - and still connect up to three 4K displays.
