No, you dont want it. You want to use the integrated intel HD.
Your load could easily be handled by a i5-4590 available for 300.

any way to decrease electricity use - would an i7 be better?

Would probably be the same. The newer haswell/skylake systems are very efficient.

Not putting in the discrete graphics card will save on electricity. The integrated graphics on the CPU will handle the encoding with no problem.

If you're building a system you can also look into the S and T series of CPUs. Slightly lower clock speeds but improved power consumption.
