What the difference between the nVidia Quadro line and say their GTX line? Or AMD's Fire[insert model suffix] vs. their 4800's? Are the GPU's in both cases the exact same GPU? Or are workstation GPU's a different can of worms? And why do I often read that workstation cards are not fit for gaming at all. I mean they cost like 600-1200 dollars!!! That's more then the 5800 series Radeon's. So I was just looking for some clarification on the differences in mainstream individual consumer video cards, and (generally) industry used workstation cards.
