Honestly, warranties aren't worth it, and it'll just cut into getting better parts. If your set on spending 1k only. Obviously cat's build will not work as you'll be spending 1.2k or so. I'll post a build i was looking at for my brother a couple days ago. It should fit everything your looking for and for just a bit over 1k.

Obviously with more time, a better build can be had, but this is what I came up with for a full 1k Computer build.
