5800X vs 5800X3d and new here

For RPCS3, 5800X3D is slightly worse than 5800X due to lower clocks, but not by much.
It's better for native PC games due to the 3D cache, so you might want to base your decision off that instead.

Apologies for the severely late reply 

I went with the 5700x3d, could not justify the 58x3d as I picked the 57 up for 95 on amazon new as the seller had a typo 

Performance wise I'm very happy with it and it runs most of my ps3 games very well for the most part with some games running poorly but im not really interested in them as I have the pc versions 

Mgs4 runs at about 60avg a lot of the times and dips down but way better than the ps3 ever did
