I am about to buy a SP4 on Craigslist from a local seller. It is listed as an i7 with 265 storage. I want to ensure the CPU is indeed an i7 when I get there today. What is displayed when selecting My Computer, Properties ? Intel Core i7 - 6650U? (for example, my SP2 shows the following: Intel(R) Core(TM) i5-4200U CPU @ 1.60GHz 2.30 GHz). How else could I ensure it is an i7 when I boot it up before purchase? Thanks!
