<cc_config>
<options>
<ncpus>7</ncpus>
<use_all_gpus>1</use_all_gpus>
<ignore_cuda_dev>1</ignore_cuda_dev>
<ignore_cuda_dev>3</ignore_cuda_dev>
</options>
</cc_config>

The lines in green should make BOINC ignore the second GPU in each of your GTX 295 cards. But ISTR with fairly recent drivers CUDA isn't affected by the SLI setting anyway...

I'm interpreting the cc_config doc in the blind, since I don't have a CUDA capable card. So if someone else with real experience corrects me, believe them.
