What would you upgrade first?

Ok for context I am racing on iRacing on a Rtx 2070 and an intel i5 9600k on a single monitor. I also have the thrustmaster 248 with the pedals set and the mob for the break from 3Drap on a computer table and pedals on the floor.

The question is, what would you prioritize first. My thoughts were the next level wheel stand 2.0 > simjack pedals > base + wheel > computer > and chair upgrade at the end.

Which upgrade has been the most significant for you? And the most fun?

I am really looking into hearing from people upgrading their entry level set ups and know which one keep you hook up on the sim.
