The Cohhilition

Where should I make my next upgrade? I was thinking maybe the GPU or Storage.
I eventually want a PC that can handle streaming & gaming at the same time. I recently just got this i5-7500 for $139 at Fry's. Previously had the G4560 as a place holder.

While I would normally suggest an upgrade in GPU, it looks like you could get a substantial upgrade in terms of CPU. This would especially be important if you want to play and stream from the same computer.

I would definitely say CPU if wanting to stream.
