Hi, I am planning to get a new desktop. I already ordered 7950x, and I almost decided to get a 7800xt. Probably I'll get 96GB RAM or more. What would be a good motherboard and PSU for this setup?
Probably I'll try a x870 board. I heard some good things about ASRock Nova but also heard it is out of stock and will be out of stock after like 5 seconds after the restock. I also saw some positive review about Taichi but its kinda expensive and probably Nova is already an overkill for me.
I liked my MSI boards but I heard they don't support ECC which I am not familiar with. I'm not sure if that would matter for me; my main use will be some heavy computation that can take several hours to several days, plus some games. Does this sound like something that benefits from ECC?
Also how many watts do I need for this, and is there any specific product you would recommend?
Thank you.
