So I recently got around to go for upgrading again after a "longer hiatus" from having gotten X99 when it was brand spanking new and also again getting the 5th gen CPU's when they came, mostly because I was using it for both gaming and a lot of rendering (3D modelling, CAD, rendering music, etc), so I needed some form of workstation-grade capable hardware.
Now I find myself once again getting around to upgrading, so I managed to snag myself a nice 6900XT and I'm wondering what motherboard to pair with the Ryzen 5950X. But I'm "so out of the loop" that I'm not entirely sure where to start looking anymore, and seeing mixed info on what motherboards and chipsets support ECC and which ones that don't. I would probably prefer having ECC due to rendering etc, as I'm sure many of you can understand, so the whole confusion when getting back into tech stuff again is maybe slightly obvious, but I am going AMD this time around. I tried searching and looking for answers but it honestly didn't make me any less confused.
Was taking a gander at the ASUS ROG Crosshair motherboards, but they almost seemed over the top, but the WIFI I/O ports at the back were a nice one (though I am not averse to a WIFI PCI-card if it is included). Though slightly pricy for what they seemed to offer.
So tl;dr:
Which chipset should I be focusing on?
B550 or X570?
Which MOBO?
Support for ECC or not?
Fitting MHz for it?
Most likely getting 64GB of RAM, may or may not also be used for Star Citizen as well (but ignore that part), but rendering has a tendency to be more efficient with 32 and up.
Focus on ECC or just go for non-ECC ram?
Preferably one that fits a Noctua NH-D15
Any and all help making up my mind is greatly appreciated
