As spec'ed, the AMD build has a much stronger GPU. If this is for games get that one.
Otherwise, the Intel build can be made a lot better than it is. First of all, with a locked CPU, you won't be overclocking, so you can lose the cooler and save that money. Put it toward a better PSU; for that one to have an 80+ rating suggests it may not be junk, but RAIDmax is known for PSU-shaped objects and is not to be trusted. A model like the XFX one in the AMD build is much better. Hopefully you can also get a better graphics card. I'd get at least a R7 260X or GTX750Ti, although of course the R9 280 is stronger.
