High End Gaming PC £5000 Budget

Hello there, I am new to the PC creation scene and my first post, so I apologise in advance if I've done something wrong.

The main purpose of this PC is high-end gaming, with the intention of making videos from my gameplay. Photo and music editing will also be other uses.

The factors that I would like to keep are the Graphics cards as I like the look of Nvidia Shadowplay (Unless you have a really good Game Capture Software with better capabilities). I would also like it to be silent, or as close to it as possible. Lastly, I would like it to be able to be dual-monitor ready, in case I buy another monitor soon.

Here are the current specs:

My comments:

CPU - Went for the i7-4930K because the i7-4960X seemed a bit overboard and nearly double the price of the former for not too much more power.
CPU Cooler - Seemed to be the most popular on the thread, however is it quiet? I've looked around and it has had mixed reviews about the noise levels.
Motherboard - Went for the Rampage IV Black Edition because it looks cool, but will the ASUS P9X79-E WS be better?
Memory - Went with the Platinums because they seem to be the best.
Storage - Seems enough and good quality, but would like to know if that is a good setup.
Video Card - Went with the quieter Direct CU IIs and also went with Nvidia because of the Shadowplay which I intend to use.
Case - Don't know yet, put the corsair down, but still not sure whether to use this or the Fractal Design Define R4 Black Pearl, which is said to be much quieter.
Power Supply - Too much? The estimated wattage was about 900.
Optical Drive- This had good recommendations but don't know if this is a good option.
Monitor - A 1440p monitor was recommended and this seems to be a good one. The 32" seemed huge ( I have some TVs that size:L ) so for my desk this seems a better option.
Sound Card - I know slightly unnecessary, but I might be doing some recording soon and want good quality.
WNA - Is this a good one? Also don't know much about these.
Case Fan(s) - I went with the Corsairs because they are not the brown colour of the Noctuas and also they seem to be quiet. Views appreciated.
Mouse - Went with two because I like a 12 button grid for MMOs but hate them when playing other games, so just put both in there.
Headphones - I really like Corsair headphones, I had a pair in the past and they were great!
Keyboard - I really like Razer, but I'm not sure which style to get. If any better options, please say

Thanks in advance!
