What GPU for power efficient mini ATX workstation?

Hi!

I got couple old parts left so I’m building cheap small factor workstation for myself. Something that I can put on my desk that looks nice.
Goal of it is to be cheap and power efficient.
It will not replace monster build I have.
It just have to run UE4 good.

This is what I got from old parts:

  • Pentium G4400
  • 16 Gb RAM
  • SATA 320 GB HDD
  • 350W PSU
  • Nec 20WGX2 (1680x1050)

This is what I will add:

  • MiniATX H110 motherboard
  • MiniATX Case

But I need GPU for it too (beside the one built in). I’m thinking about those three:

  1. GTX 750 Ti 4Gb.
  2. GTX 750 Ti 2 GB + SSD 120 GB (to replace older drive I want to put in it + GPU is low profile, so I can pick even smaller case)
  3. GTX 1050 2 GB.

All three options will be around the same price in my country.

What would you pick? (And no, I don’t plan make my budget bigger for it.)
