B550 or X570

[smrtblue]

Looking at building a PC with close to these components, I can't figure out if I should go with a B550 or an X570 mobo, I need to find one that does support a front USB type C.  The GPU may change to something new that hopefully will release in the fall.

If you don't know why you might want X570, then B550 is probably the way to go for you.

 

Basically X570 has more PCIe 4.0 lanes, so you can have more very fast storage, which most people do not need.

B550 allows the lanes that are connected to the cpu to be 4.0. If you don't need the extra 4.0 lanes then b550 is more than enough.

Budget? 

[Mateyyy]

Basically, with X570 you're getting PCIe 4.0 lanes from the chipset and a little bit more USB bandwidth. B550 is enough for the vast majority of people, since well, most people don't throw in three PCIe 4.0 NVMe drives as well as other add-in cards in their systems.

 

I changed around your parts list a little bit:

^ including a solid B550 board with an internal Type-C connector. Though I'd suggest waiting for Ampere and RDNA2 GPUs to release first, then get the components.

 

Also, if you're just gaming, a 3700X and 16GB of RAM will perform pretty much identically.

If you don't know wether X570 is relevant to you, it most likely isn't. PCIe 4.0 is ... irrelevant to 99.9% of the users at the moment and most likely even in 1, 2 or 3 years of time (people still use SATA SSDs and are content with the performance, there's not MUCH to gain from jumping to NVMe if you're not handling lots of files, the increase in overall feeling is small and many people can't tell the difference). You'll also have the option of PCIe bifurcation on X570 - which is great if your that .001% of users who make use of that. It could also be added down the line to the BIOS of B550 I guess. 

 

Bottom line: you're fine with B550.

Make sure to check the Type C header as some are only 5Gbps instead of 10Gbps. The B550 Tomahawk above for example is only 5Gbps. The X570 version has a 10Gbps header. So a 5Gbps will still work, but you will only get half the speed.
