So far, on my GTS250 1GB:

1x BRP4 - approx. 1h35min
2x BRP4 - approx. 2h18min

I did not try 3 tasks at once, even 2 parallel tasks make video a little jerky.

ouch!

since you are hiding your hosts, that info is pretty much useless.

we do need info about OS, HOST-CPU, type of the app you are running and if you are sparing cpu-cores for the gpu-app(s).

probably clock-rates of the gpu would be interesting too.

i can tell you that my GTS-250 finishes current tasks in about 60 minutes.

but that's a PHENOM-II 940 @ 3.3 Ghz, UBUNTU-64, BRP3cuda32nv270 app with a spare core for the GPU-app. and the GPU is slightly overclocked about 10%.

Well, frankly I prefer not to

Well, frankly I prefer not to share everything about my computers ;-)

But in this case:
Ubuntu 10.04 32bit, kernel 2.6.32-33, Boinc 6.12.33
Athlon2 3core 2.5GHz, unlocked, all 4 cores calculate S6Bucket (!)
4GB RAM
GTS250, 1GB, GPU 738MHz, Shaders 1836MHz, Memory 1100MHz

1x BRP4 - approx. 1h35min
2x BRP4 - approx. 2h18min

I did not set any exception in terms of nice/process priority.
Info about next gts250 running on WinXP will be posted a bit later
