The GPU is not going to be of any use - it's way too old.  If it could even mine, it would never make enough to cover the cost of power used to run it.

You could run 4 GPUs off that motherboard, but keep in mind that the CPU is power hungry compared to a newer proc.

I'd be very wary of an older PSU like that - it's at least 7 years old, as BFG Technologies closed down in 2010.  Even if BFG were still running and had been known for quality (they weren't), a PSU from 2010 is going to be really inefficient.
