The Intel build is better.
Even though the AMD build's processor has more cores, the Intel still outperforms it. This website will tell you why:

The Intel build's GPU outperforms AMD's. But if you're going to run at higher resolutions than 1080p, I recommend the R9 280x since it's 3GB instead of 2. This link will tell you why the GTX 770 is better:

For the other specs, they're the same in both builds. So the winner is Intel.
