The 7900/7950x3d chips are out now, with the 7950x3d looking to be the new king for this sim, but 7800x3d is due out in early April. Those two CPU’s are expected to perform about the same in gaming because the 7950x3d essentially cuts out half its cores and turns into a 7800x3d. If you have a ton of add-ons, the 7950x3d may be the better option (yet to be tested because AMD did not allow reviewers early access to the 7800x3d for comparison), but it’s also $250 more than the 7800x3d will retail at.
If you are already looking at spending that kind of cash on upgrading, those are worth looking into.
