So, as the title explains, I am debating over the Mobo for my new (and first) build.
I'm probably going to go with a 4790K, 16 gigs of DDR3, but still deciding on the GPU.
I know there's not a huge difference between the two, but I'd like to know if it's worth shelling out a little extra for the features which lay within.
Also, I know that the Gaming 5 has an M.2 slot, but since I'm regardless of this build getting an ultrabook which has an M.2 SSD, is the slot on this motherboard hotswappable? (I'm guessing no)

If there's any other cool features that the latter one has as opposed to the first, please let me know.

Thanks in advance,
