What game should I benchmark on my Optiplex 7050 SFF?

Will be benchmarked on an i5-6500, HD530, 8GB DDR4 2133mhz single channel and 237GB SATA SSD.

Currently the options are:

DOOM 2016

Oblivion

Assassin's Creed IV

Metal Gear Solid Peace Walker

Comment which one, the benchmark will be out by Saturday to Monday.
