Not a lot different from the FE in performance, but quieter, cooler.
The extra hdmi, the case fan plugs etc make me think the different is worth it.
Although the price they went with in the review was a little optimistic.
Nice card! But 30% faster than the standard 1080 suggests that it isn't "mustard" when it comes to SS: 1 and HMD-Q: 2.
I'm actually relieved that I don't have to splash again so soon. My wife would kill me.
