actually I was surprised at how good the experience was, considering I was really disappointed with my previous nVidia Shield Tablet and it's streaming.
My host is my MSI GS70 running i7, 16Gb memory and nVidia 765M.
Client is my new iMac Retina i5, 16Gb and M290X.
Using Aztech 5ghz power plug wifi thingy, and the streaming is really good!
