Cuda on single GPU

I’m new to CUDA and looking into it for scientific computing. Is it possible to use a laptop with a single GPU for CUDA applications?
What are the implications, can windows use the display while cuda code is running?

I have a laptop with a Quadro FX3600M and Windows 7. I will probably be using Visual studio 2010 and Nsight for writing code.

You can use CUDA with a single GPU, but you can not use NSight. Also CUDA and the windows desktop can run in parallel.
