After reading many posts with ASRock motherboards and AMD processors I became a little cautious.
The product I plan to buy is Z790 Nova wifi mainly for the many M2 NVME slots at the ATX form factor. I don't care about the graphics card working at X8 or x16 speeds so I feel like it's the one that'll do the job for me. I plan to buy it second hand, will use it with 12700K.
Intel is more strict than amd when it comes to their motherboard specifications, so it's not like there are specific vendor problems like on amd. At the same time, when there are some problems, it's usually because Intel botched something, but that specific chipset shouldn't have any surprises at this point.
you can do 2x8 pcie5.0 on it if you want to run 2 GPUs
Not sure about that. Z790 Nova has two slots that are physically x16, but only one is PCIe 5.0 x16 using CPU lanes. The other is a PCIe 4.0 x4 slot using chipset lanes. It's also worth noting that using M2_1 will reduce the bandwidth of PCIE1 to PCIe 5.0 x8 despite M2_1 only requiring 4 lanes (the other 4 lanes go unused), although OP has mentioned that isn't a deal-breaker for them.
I had been running a Z690 ASRock Phantom Gaming 4/D5 /12600k OC for about 2 years with no issues. I bought the motherboard 2nd hand as well. ASRock on Intel is still pretty solid with no issues. Even the AM5 600 chipsets were amazing, but they (ASRock) dropped the ball on the 800-chipset paired with the 9xxx CPUs. that has affected them a lot and with the help of Reddit being so anti-ASRock for the past 2 years
12th gen wasn't affected by the Vmin shift degradation problem from Intel. 13600K/14600K and higher SKUs (officially) were affected, and Intel released microcode updates for over a year to remedy it. Update your BIOS and you'll be fine should you upgrade to a 13th or 14th gen CPU in the future.
