Advice for Gaming/ Minor Workstation Build?

[wookiemangreg]

So this is my first computer build, and I want some more advice before I purchase anything. I don't really have much experience with actually building/ choosing a setup, but do have a general idea of what I want. First off, here is the link to my build:

So this rig is going to be used for gaming as well as engineering programs. I am going off to college in a few months, and wanted to make sure that I not only had a pretty good system now but for the next 5 years or so.

I have a few questions:

Are there any compatibility issues, or is everything going to work just fine?
Are there unnecessary components I have chosen that I could go with a less expensive option?
Are there any things that I am missing that I would need?

I chose the monitor (BenQ RL2455HM) because I already have one of this type, and want a dual monitor setup (do not bother with suggesting a different one). The Razer Deathadder is a quality mouse at a reasonable price, as well as the Razer BW UE. If there are actually better options than these two at a LOWER price, I am open to suggestions.

Any advice is greatly appreciated!

the parts you have chosen are for heavy overclocking, if not doing this, there are cheaper alternatives which wouldn't affect performance noticeably.

-The Hyper 212 EVO is plenty enough for basic systems and moderate overclocks.
-Dropped the extra thermal paste. It's a waste of money.
-No need for an expensive motherboard. The Extreme4 has everything you'll need. You'll only need a more expensive motherboard for a more aggressive overclock.
-16gb of ram is plenty for your programs.
-620w is plenty for a single gpu set-up. Since you don't plan on doing a SLI set-up, no need for more wattage.
-No need for the professional version of Windows. Also, Windows 8.1 Update is proven to be faster in games and you can make it look like Windows 7 with free programs like Start Menu 8.
-IPS monitor for better image quality.
-Better quality keyboard. Ducky keyboards are much better quality than Razer and it comes with Orange LED backlighting with some unique backlighting features. If you dislike the Orange color, then simply just disable it and leave it as a regular non-backlit keyboard. It will still be better quality and worth the $30, IMHO.
-The Deathadder 2013 is a great mouse and a better choice over the Abyssus.
-Razer headsets are decent, but I prefer the Logitech G930. You have the option to go either wired or wireless and the sound quality is fairly good.
