So your choices are as following.
1: The "PALICOMP NVIDIA Gaming PC" comes with an acceptable CPU but crap GPU.
2: The "PC Gaming PC Quad Core intel i5" comes with a good CPU but crap GPU.
3: The "ADMI GAMING X4 860K" comes with a crap CPU but decent GPU.
I you forced me to buy one of them, i'll go with the second one and then replace the GPU as soon as possible.
But I would rather buy ether this
They both perform the same, but case is different.
They step down the CPU just a little bit compared to the second of your 3 computers, but adds the graphic card from the third system. And that graphic card is actually decent for modern gaming.

If you can wait 2 month or so, you will get a better deal on a computer with the upcoming 1060.
