Is this upgrade worth it?

[HardwareFanatic]

Hi all I wanted to make an entirely new build but then I thought that I didn't need a new one, I just needed to upgrade
I'm coming from an AMD 8150 @4.4Ghz, Sabertooth 990FX MB, 8Gb G.Skill Ripjaws RAM 1600Mhz, GTX 580 GPU.

These are my planned upgrades.
