I need help building a PC for smooth unreal development

Hi, currently my PC is very slow in unreal, the launch time is slow, the interface is laggy and as a programmer I need to compile my code quite regularly and it is taking 100 seconds which is unacceptable for my workflow.

My current pc is about 4 years old and I have worked it hard so I want to build a completely new computer, but budget is an issue so I am thinking of going down the road of building an AMD system.

Could someone recommend good amd parts that would be able to smoothly run unreal.
My budget is £1000.
