Mostly gaming. A little bit of movie watching and video editing. And web surfing as well.
So far the benchmarks are crazy and I'm really happy with it.
Few problems that people should be aware of. My Fractal R2 case was warped slightly on the motherboard area. Made it impossible (and stressful) to get the I/O ports to line up and the screws in. This also caused a sever issue with the GPU because it wouldn't line up at all. I had to remove and remount the whole mobo with the gpu plugged in to it (stupid me, I already had my cpu cooler on as well, so that had to come off).
Only other issue was the RAM was almost impossible to click in. You had to apply a TON of pressure. I was sure I'd broke something. But once it turned on, everything worked.
