Which Gaming Rig Should I Get?

I like the i5 rig better as well. But I'm curious, why did you select that motherboard? Are you looking to SLI down the road? If not, you can do an H97 build for less. You also don't need 2133 memory, it will give almost no extra gaming performance. And pick a more reliable PSU like a Seasonic or XFX.

You can try a build like this and save over $100, or spend that $100 on an SSD.
