While I don't have the SP3, I can tell you I have something similiar. Core i3, 4 gigs ram ultrabook. You said you want some light gaming. I'll tell you right now this processor and 4 gigs of ram is ATROCIOUS for gaming. I can't run things much more than Don't Starve and Technobabylon without the thing going belly up.
I mean light gaming like candy crush or other crap like that just to pass some time.
Also ran wow on an AMD A6 from 2012 and ran some other games on that fine. Also ran most of those games on an AMD from 2009 laptop.
