I recently had to upgrade for work (my old PC was about 8+ years old) and went with a prebuild PC from iBuyPower; Y60
- Ryzen 9 7900X CPU
- NVIDIA GeForce RTX 4070 Ti Super 16GB GPU
- 32GB DDR5 5200MHz RAM
- 2TB NMe

It has 2 slots in the back for additional internal harddrives.  I so def made use of those too. 
I'm sure there are better ones (there always are) but this is working out pretty nice.
