I bit the bullet and ordered a package from from Dell – not quite a Cadillac, but my sense is that it will more than do:
*AMD Ryzen 7 3700X (8-Core, 32MB L3 Cache, Max Boost Clock of 4.4GHz
*NVIDIA GeForce 3070 8GB GDDR6
*Liquid Cooling and 550W Power Supply
*32 GB Dual Channel HyperX Fury DDR4 XMP at 3200MHz
*1TB M.2 PCle NVMe SSD
If had wanted to spend another $1000, I would have gone for the 5th generation Ryzen chip and a 3080 video card, but enough was enough!
Should have the new unit by the 18th. May revert to you all when I have it running for advice on settings. Enjoy your new ride.
