I would think 10,000 is a good start. You may want to try random pointSizes
as well.
If the rendering of the particles is suficently fuzzy, fewer larger
particles should be required.
If the particles are more defined, you'll need a lot more of them and
they'll have to be smaller.
I've done something similar to what you did. I wasn't happy with the
results, the edges of the antialiased points were still to sharp.

1.2beta, and rendering 10 000 particles seems to run OK.
How many particles are needed to make a cloud?
