Answer 2

The build it yourself one but I'd change that fx 8350 to an i5 cuz the i5 is more upgrade-able. Could you also specify the rest of the build in number 2.

Answer 3

The second one. The first one gave no option for a GPU, while the second one has a really high end GPU.

Answer 4

The second option will preform better. But if you want to really push it and are biulding it yourself get a motherboard wich can overclock it will result in better expierience for gaming
