Rfriese.. sounds like a nice build.. other than the geforce vid card.  Nvidia has horrid open-cl support.  I'd go with an ATI card.  Other than that, beautiful setups.  Any intel cpu that is of the sandybridge chipset is a monster.  Have you compared the performance of the i7-3930 over the i7-2600?  The 2600 is still outperforming newer, faster and bigger chips when it comes to 3D rendering
