I'm seeing about 40% CPU usage on my Intel Haswell NUC 
That's just on 1 core, the other ones don't seem to be used much. This is on a 4gb 720p encode.
Like I've said multiple times, x265 CPU usage has been vastly overstated. It's EXTREMELY CPU intensive to encode, but decoding isn't that bad.
It's not overstated. Using the lowest-profile of H.265 at a low bitrate, just about anything can playback the file. It's not hard to find an H.265 file that will bring most of your computers to their knees, and those are still using the Main 8 profile.

Well I watched 2 encodes using hevc at the weekend and playback was flawless. It wasn't so using VLC on my Mac (which is actually more powerful than my NUC). It took me less than half a day to make the modifications to XBMC/ffmpeg (not including all patches..), compile and test.
No the file sizes aren't huge (neither is the bit rate) but I had no issues at all. If somebody has a more stressful HEVC sample I'd be willing to test it.
In one to two years will be seeing HEVC decoding acceleration in the GPU anyway (or maybe sooner!).

The limited amount of encodes I've seen available seem to be offering no more than a 20% saving therefore suggesting to me that HEVC isn't being fully utilised yet, even the NFO's that come with these files say they are purely the results of experiments with the encoders and not intended to be mainstream yet.

I'm not surprised jjd-uk. Hence why I only follow it loosely and don't really think it will come to fruitation until the end of 2014. It's a new standard, and people are still figuring out how to encode with it.
I hate to say it, but there is usually one major "release" that people follow. Awhile back it was axxo, now it's yify. I really think it will be when yify starts releasing things in x265 that there will tons of posts on here asking "Why can't I play movies in this new format!!!!?!?!?!?!?!"

yifi is crapola of the highest order.

I tried the ~8000kbs 1080p video on the elucard website on a 800mhz i7 ultrabook and CPU usage was around 70%, video played without a hitch. Not sure how that sample rates in difficulty to decode though. Does anyone know of a x265 equivalent of 'killa sample'?
