Alberthan :
I have a 770 pc at home. Ermm so shield will get more fps at emulators and games than the note 3?
Not sure what you mean.
Shield works two ways:
1) Streaming from your PC
2) Android for games on the Shield itself.
Only the Android games depend on the Shield's processing capabilities.
Again though, you are comparing two completely different products. The Shield has the disadvantage of a small, relatively low-res screen but the big advantage of the great controls and streaming capabilities.
Personally, I love the Shield concept but the screen is simply too low-res and small for me. You can simulate the screen on your own PC like this:
a) scaling on monitor (NVidia drivers)
b) map 1:1 pixels (monitor settings)
c) set screen resolution to 1280x720 (should now have BLACK BARS around all edges with an actual 1280x720 pixels)
d) hold a RULER out at the same distance you'd hold the Shield, then move your entire body until the viewable diagonal matches 5"
Now you can see what the screen looks like. Try running a few different games. Some like SKRYIM are okay, but others don't look very good at 1280x720. For me, dropping from a 2560x1440 screen it was just too much (plus I have no need for local streaming).
