game development pc build

I need a new game development rig, 'cause i own a dell 7567 laptop with i7 7700hq and gtx 1050ti but I need more performance. I think this is a good one, but I’m not shure if i should put more moeny into the cpu and less into the gpu.
The price of this build is 1250 in my country, and that is my budget. Your advice will really help me out
