I have a Quadro FX 5600 and I'm running at about 26.4 Mhash/s. Does that sound correct, or low?
sounds about right. the Quadro FX 5600 uses the G80 core and is essentially the same as the 8800 ultra.
Very interesting, thanks for the information. I started it up on my other computer with a GeForce GTX 465, and am getting 63.5.
yeah, the 8xxx series is the first generation of GPGPU, so it's not overly quick.
Now don't laugh, I'm just testing this to see if it works.

I have a laptop with an ATI Mobility Radeon HD 3650. Should this miner work with that? All it shows is the CPU and not the graphics card.
My desktop has an Nvidia graphics card. Am I out of luck there or is there something similar for that?
the 3xxx series of ATI chips don't do opencl, so you're SOL in that respect.
as for the nvidia in your desktop, it will work if it's a 8xxx series card or newer. you may need to update your drivers for it to work.
