Currently I have 2 systems:
Upgraded system 5800X3D and a RX7900XTX
Old parts 5800X and a RX6750XT.
Apart from the GPU upgrade the only difference I found with the 5800X3D is Benchmark #'s between them.
The 6750XT had both CPU's under it.I only upgraded as It was a last upgrade for awhile(riight).
The 5800X is at a good price right now.
I hope that makes some sense.
