I bought a motherboard for my incoming i3 9100f because it said on newegg that it was a 300 series MB. The MB showed up the day after I ordered it, but nowhere on the box says it's a 300 series MB. I confirmed that the processor would be compatible before I ordered it, but I'm concerned because nowhere in the instruction manual mentions "300 series". It's a B360 MSI board. The CPU is supposed to be without graphics, which is what I want, since I have two GTX 280s to plug into it, but the MB has a video out on the IO. I guessed that must be for the BIOS, but now I'm not sure since that doesn't make sense...? Did I make a goof and order the wrong stuff? Or will these things work together?
