The first step in solving any problem is to properly define what exactly is the problem.
This is easier said than done simply because we can sometimes only see or notice the symptoms of a problem or the results but not the cause of those symptoms/results. The cause is the real problem which may be very elusive or just too complex to define.
So identifying the actual problem is the most important first step to solving it.
I would try going to pcpartpicker.com and build your pc from there, and after you’ve done that take your remaining budget to find whatever else you need for your setup
