Using the beta demo 2.46 benchmark scene with unmodified settings and no viewpoint change a FX 1800 got aprox. 1.15 Ms when it settled down compared to a 3.1 Ms with a Quadro 2000. The Q2000 has three times the CUDA cores and the rendering speed difference is aprox. 2.7x better. If you take into account that the FX1800 clock rate is 1342MHz and Q2000's is 1221MHz, then if the Q2000's core would be as high, the difference would be close to 3x again. This means that the cores scale really well. Twice the cores, twice the performance when everything else being equal.
The Quadro 2000 card is a loaner, probably going to substitute it with a GTX 560 Ti 2GB version. With 384 cores and a shader clock rate 1645MHz I'm expecting around 8.4 Ms in the benchmark scene. I don't want to get the GTC 470 as its power draw is significantly higher and I'm liking the 2GB memory on the 560 Ti (+ significantly cheaper).
Setup: Win7 Pro 64bit, XEON X3450, 8GB RAM, Quadro FX 1800, Quadro 2000 for rendering (going to change to a GTX 560 Ti 2GB for rendering).
