At 1440p 110Hz you'll probably want another GPU and a 850W PSU (if you are planning to do any OCing as well), for a single GPU you could drop it down to a 600~650W PSU. Not sure if you need 16GB RAM, as you have an i5 I would assume 8GB would work (and you can upgrade it to 16GB later as well, unless you think you'll need 32GB RAM for some reason). I would also consider going for mid tower rather than full, since it'll still fit dual GPUs but be a lot smaller and cheaper, the HAF XM looks similar to the HAF X if you like the design. Samsung has the 850 Pro series as well to replace the 840, however Crucial has the newly released MX100 which is
a lot cheaper but still has good performance so I would get that. Blu-ray/WiFi card are up to you, don't make use of either them myself.
I wouldn't spend the extra for the HERO VIII, it's simply not worth spending that much on a LGA 1150 board. If you have money to spare you may as well spend it on an LGA 2011 MB + -E CPU so you can get PCI-E x16/x16 rather than x8/x8, although there might not be much of a difference (0 if you stick with a single GPU).
So something like
this with the extra money being saved up for another GPU if your monitor does actually successfully OC.
