Questions about MSI H81M P-33

Hello! Seems like I've been working on this PC build for years now.... oh wait I have lol (this is my first time doing this). One thing comes up, then another, you know how this story goes I'm finally getting back around to it. When I started building it I was going to go with an ASRock mobo, don't remember the exact one but now a year later they're completely sold out everywhere I look so instead I went with the MSI H81m P-33, because of its price. Now I have a few questions, here is the relevant info with my build first though:

Mobo: MSI H81m P-33
CPU: i5 4460
GPU: GTX 1060 (not sure which one yet)
RAM: 8GB (2x 4GB) Corsair Vengeance DDR3 1600
Case: Source 210 NZXT (cant remember details right off hand, but its NOT the elite version)


So basically I just want to know if this will all work together? When I plug all this into a build on pcpp there is a warning that pops up that says there is a potential incompatibility between the i5 4460 and the mobo, something about maybe needing a BIOS update before a haswell refresh cpu will work on it? Will I need to update the BIOS, and if so, what is the best way to do so?

Will a 1060 work with that mobo? I don't see why it wouldn't but I figured I'd ask to be safe.

Also, according to reviews this mobo doesn't have any USB 3.0 headers, but for me that's ok, the case I have only has USB 2.0.... I can't seem to locate any info on weather or not there are USB 2.0 headers or not on this board, so are there? I legit have never used front USB for anything but very light data transfer (pictures, and some video), so I don't mind the difference in speed between 2.0 and 3.0.

I have purchased the entire build except for the GPU, CPU, OS, and a planned SSD, so if this mobo is incompatible with my cpu OR gpu I'll just return it and get something else. It's a weird build, I know, I was aiming for inexpensive on everything but the CPU/GPU and I think I did ok, my original goal was 700-800 USD and I hit that pretty perfectly, I just hope it all works when I put it together (once again idk why it wouldn't but this is my first build and I freak out a bit when it comes to details).

All I plan on doing with this machine is web browsing, and some 1920x1080 gaming. If there was some place where I could have found all this out and I made this thread for nothing, I apologize, I am new to this. Also, if you have any questions at all feel free to ask and I'll answer as best I can.
