Alright,

Looking to move to AMD come zen3, just figuring out what mobo would best suit me as I'm a tad confused on lane usage.

I'm looking at the below first, not a strict budget but not keen on much over £200+, have a pcie wifi card and 2 x m2 ssd gen 3 and will likely get a 3080.

Open to other suggestions on boards also, will likely chuck a 6 or 8 core in depending on AMD's offerings. No extreme overclocking

Just curious, if im running 2 x M2's a gpu in the top slot and a pcie wifi card in the bottom slot. Would this effect the top PCIE slot at all?

My basket at Overclockers UK:
Total: £326.04 (includes shipping: £11.10)​
​



Cheers

With the MSI on sale, I'd probably go for that. Both have great VRMs though and will be more than adequate.

B550 has PCIe 4.0 lanes distributed so 16x top slot (usually GPU), top M.2 slot is PCIe4, and the remaining PCIe slots and 2nd M.2 being PCIe 3.0 lanes. With X570 boards, every slot is PCIe 4.0.

So shouldn't have any issues on B550 if your M.2s aren't Gen4. The top lane for GPU will always be PCIe 4.0 no problems.

noob question, with those slots filled the top lane still runs at x16?

Yes, it's a dedicated 4.0 slot with 16x lanes - same as X570 top slot is, just with B550 it's the only 4.0 lane - whereas X570 every PCIe lane is 4.0.
