I have two CUDA enabled GPUs on my machine. However, BOINC doesn't want to use the second one.
NVIDIA GPU 0: GeForce GTX 260 (driver version 19038, CUDA Version 2030, compute capability 1.3, 896MB, 537 GFLOPS peak)
I know, the second GPU is slightly less powerfull than the first one, but it's still able to compute data.. Is there a way to make BOINC use the second GPU too?

Check your BOINC data directory for a file named cc_config.xml. The path to the data directory is listed in the Messages tab of BOINC manager after a reboot. The directory may be hidden by windows and it contains the file client_state.xml (and many others).
If you don't have a cc_config.xml, create one using notepad (Editor) and paste
<cc_config> <options> <use_all_gpus>1</use_all_gpus> </options> </cc_config>into it. When saving, make sure that no other suffix (.txt) is appended to the filename.
If you already have created a cc_config.xml file, add the <use_all_gpus> line to the <options> section.
After that, select "Read config file" from the Advanced menu or, better yet, restart BOINC.
