R5 2600 only includes Tom Clancy Division 2, 1060 3gb is a pretty bad card for 200$, but the R5 2600 isn't overkill for the 1060 3gb although it doesn't bring out the r5's full potential since it can handle stronger gpus.
It is a great motherboard but to find what you're looking for, always look on the manufacturer website. Newegg wasn't wrong either, it does have a USB Type-C, they just don't specify whether it was on the rear or front.
MSI has the tomahawk specifications on their site, it says that it only has the Type C Gen2 on the rear, no front header. Check some other motherboards supposedly of higher quality. (Higher quality = Maybe some x470 boards or the b450 carbon from MSI)
