Help me choose a motherboard

[Roguiber]

Hi Guys

I have purchased the following components but I'm wondering what would be the best motherboard, considering I'm thinking about adding another NVME to the build later (And I have 2 SSD Sata)
I was thinking about a MSI MAG X870 TOMAHAWK WIFI ATX AM5 Motherboard but I read that when m.2 slots are being used and one of the m.2 slots being pcie 4.0x4 instead of pcie 4.0x2. An I'm not sure how that would impact me.

The more commom the board the better, since I live in Brazil and we don't have a lot of options.

You don't want to use the Shift psu with that case. Use a normal ATX 3.0 / 3.1 psu. If your resolution is 1440 then look at a 5070 Ti and you can save money by going with the 7800x3D.
