Anything not really necessary? How long until this will get outdated? I want to have this for gaming for 4-5+years. Are all these parts suitable with each others? I also want some of your suggestions for different parts. Thanks,

Setup looks fine. But PSU is a bit overkill. That system could run on a 500W, but would be good with just a 600W.
What's the price? It's usually a better deal to assemble it yourself.
If you want it to be able to run games in 5 years, which is nearly impossible to make sure it does, I would upgrade the GPU to a GTX 770 at least.

RAM - 2 x 4GB.
Mobo & PSU - Don't need 990FX + 800W unless you plan to SLi in future.
wifi - dual band?
May be SSD? hybrid drive is not as fast as SSD.
Soundcard - get Asus? The review for that creative from newegg say there is driver problem.
