True full specs do help, not much of a gamer on odd occasion may play mostly Photoshop, Cad/Cam 3D but have to admit FireGl V7700 was a great card in it's day it doesn't play as well as one would think with some Cad/Cam programs which lean more to Nvidea......Cad/Cam 3D usualy aren't concerned of rendering so much yes use wire frame and rendering but not to the photo realistic that an Engineer would want to s see his creation.
System in current build.
Asus P8P67 WS Revolution Rev 3
Intel I7-2600K ( choose this over I5 for the Hyperthreading used by most Cad Programs)
16 GB Kingston Hyper X 1600 DDR3 ram
Kingston Hyper X 120gb SSD SATA 3 (OS/Programs)
Kingston Hyper X 240 gb SSD SATA 3 ( working storage)
2 WD Black 500 GB SATA 2 Raid 1 for final storage, archiving (already had these but did consider 2 velociraptors)
So was considering a Graphics Card and was kind of leaning away from workstation class
HD6870
GTX 560 DirectCu II Fermi
GTX 460 Fermi
Quadro 4000 (but not sold on benefit over gaming cards)
