Have a PC but have been experiencing random power resets since build. I've troubleshot to the extent I'm able and determined the mobo is the issue. Currently running AMD. For replacement, microcenter has a deal on an Ultra Intel 7 and AMD 7 7800X3D. Both around 400 with mobo.

Its been years since I ran an Intel chip so I'm just looking for opinions. I don't overclock...I just want stable gaming with stock settings. Thoughts on which is the better buy? I'm planning to keep the rest of my hardware (PSU, ram, cooler, etc)
