System for streaming, youtuber?

My colleague currently has a 5-digit subscriber number where quality is very important to him. Now he often has fps dropps in fortnite, and his render time is not that either.

I know that it is due to the CPU and ram.

Currently:"

I7 4770

Gtx 1660Ti

16gb ddr3

Power 11 500watt

Idea was

Sell ram, cpu, motherboard, and switch to amd.

Ryzen 5 3600

B450max board

16gb ddr4

An nvme for its programs

(he would like to have an nvme) 250GB

And a new case because his junk is there.

Budget max 400 euro

Streaming, rendering, designing.

Looks pretty neat.

If nothing speaks against it, sounds good the processor I can recommend, already installed with 2 friends, are very satisfied.
