bottleneck gtx 970 x4 860k

Solution
970 is much better and your cpu will bottleneck for sure, but still a good upgrade vs 1030, should get better FPS in those GPU demanding games. What PSU model do you have?

Not sure about the V3 . . the V2 I heard was mediocre.

I haven't found anything positive about the VTE500. I would strongly recommend coming up with a little more cash for the PSU, as you don't want something that will fail and possibly damage your PC components.
