Need Help Deciding On a System

[ge7atme]

Hi, I have been looking to buy a gaming pc for about 2 months now and I need help deciding which one to get. I found these both off of youtube and was wondering which was better.

and

I need to know which will work better on mainly gaming, which will last longer, which has higher grade components, and if you could make it any better, that would be awesome.
P.S. I can get the first off newegg for about 500 bucks, not what it says on the bottom.
P.S.S. you can also vote in the poles (I don't know how they work)

Best balanced, higher quality components and futureproofed, thanks to 6 threads and 6 pseudo cores (2 cores sharing each process in one cluster)

This will still give a good 1080P experience. This also has a very high quality semi-modular power supply unit, so you're assured stable, reliable power.
