I know this article is a bit old, but it's worth the quick read (more specifically, scroll to the 3ds Max test section).
EDIT (thanks azeem40): Here's the link:

I would suggest:
I7-3930K
Noctua NH-D14
Asus P9X79 DELUXE
(32GB as 4x8GB, for now, add more sticks later if needed) Corsair Vengeance or Dominator/G.Skill RipJaws Z
SATA III SSD 128GB~256GB such as Intel 520/Crucial M4/OCZ Vertex 3 or 4/Mushkin Enhanced Chronos (Deluxe)
Storage HDD, such as WD Caviar Blue/Black or Seagate Barracuda (LP)
Corsair Professional series AX850 PSU (also consider Seasonic USA's Platinum series PSUs for extra efficiency)
At least 16GB RAM, up to 64GB DDR3 1600MHz
PNY VCQ5000-PB Quadro 5000
Also, invest in a high quality case with high ventilation, as the processor and GPU will get pretty toasty.
Also note: make sure the memory will fit with the Noctua NH-D14
