Lower End Build for UE4/Blender beginner - suggestions please

Thanks that info is helpful. Regarding the cards. I mentioned 950 because it was newer and close (but lesser) in general performance to 770, but I note one particular benchmark it is terrible in compared to the 770 - the 3D Mark 06 test. Is that an important benchmark for using with UE4/Blender? Several other benchmarks are very close. I do like lower power consumption of 950.

Here’s comparison I’m referencing:
