Some colleagues are looking at getting new PCs for 2D/3D CAD work, and I'm helping review the spec of machines they are asking for. I was asked by the management what the difference was between the workstation cards and the consumer cards, and I couldn't answer them. On paper they seem to be almost identical. They are asking for an Nvidia Quadro FX3500 which is about £700. Yet according to Tom's Hardware it's little better than the FX1500 at half the price. It also has the same chip as a GeForce 7900 (G71) and the same memory; yet some of the key metrics seem to be worse. A 7600GT seems to have very similar capability as an FX1500... So what is the difference between the Quadro and GeForce ranges? Is there a real difference? If there is, is it worth the incredible price premium? I certainly think the FX1500 is a better choice than the FX3500 because the performance difference is dwarved by the price difference.
