Affordable Workstation Graphics Card Shoot-Out
MojoKid writes "While workstation graphics cards are generally much more expensive than their gaming-class brethren, it's absolutely possible to build a budget-minded system with a workstation-class graphics card to match. Both NVIDIA and ATI have workstation-class cards that scale down below $500, a fraction of the price of most high-end workstation cards. This round-up looks at three affordable workstation cards, two new FireGL cards from AMD/ATI and a QuadroFX card from NVIDIA, and offers an evaluation of their relative performance in applications like Cinema 4D, 3D StudioMax, and SpecViewperf, as well as their respective price points."
The workstation cards tend to have very low error tolerance, while the real time graphics cards allow for quite a bit of error in the name of speed. This is fine unless your rendering something.

Have a look at this site - it is possible to flash an 8800 GTX to Quadro FX 5600:
