Building My First PC - Stuck Between Three Builds

[KennethDev]

Hello everyone! I have had good experiences with this community in the past and I have a question.

I am building my first computer (I am 15) My budget is $400-$500 and I have created three builds that seem to suit my needs.

The first build in question is here. I realize it is pretty bare-bones, but I was wondering if it was worth it. Also, would a downgrade from the Zotac GTX 970 in the build to the Zotac GeForce GTX 960 AMP! Edition be ok? What are the pros and cons of each?

The second build is here and is already using a GTX 960 AMP! Edition Card. For this build, would the upgrade to the GTX 970 be worth it?

The third and final build is here. This was suggested to me on another forum and uses the AMD RX480.

And the final question, how would each of these builds handle games ranging from Minecraft to GTAV?

Thank you in advance for your help with my first build.

If you have an alternative build for $400-$500 (can go a bit over, it's a flexible budget) that could perform well on the suggested games, please provide it here as well. (I would prefer AMD over Intel because of what I have heard about the socket size fluctuation and the ability to upgrade)

Motherboard, the brand is good, just the chipset z170 you dont need it, you save a few $ there.
SSD, I added a SSD, which the swap of the motherboard you can almost cover this one. You should have SSD, its a must for your OS and software, it will be so much better.

And yes you should get the RX480, should be better than 960 and 970.

So with this cpu am I right to assume that I can use the PC without the GPU because it has integrated graphics? I am not saying I won't buy the GPU but I want to be able to build the PC soon (possibly before the GPU even comes out)
