It was just an example to the disprove the article's reasoning. You can modify the brands as necessary.
It's almost like they decided to completely go the other way with things because readers complained about the first build. In an effort to prove us wrong, they went from 12 cpu threads to 4 instead of 8, gave up 8GB RAM, and took out the Blu-ray drive when they didn't have to. Then were like, "Yep, we were right. The one our readers wanted us to build isn't as good." But, they didn't build what we wanted them to.
BUT WAIT, THERE'S MORE! If you're willing to sacrifice a little graphics muscle, you
can fit a i7-3970k into a $2000 computer and still have something that should game better than a GTX 670 with the added benefit of more GPU-compute performance. Just take these parts and replace what's in my first build.
