Pentium is an old series but the chips are new. It's like buying a Samsung Galaxy. The series has been around for a while now but the galaxy S5 has the latest tech. In any case, the Pentium is a budget series, lower than the i3, however the G3258 has been unlocked for overclocking and performs pretty well. It's not going to do so well in very CPU intensive games and tasks such as Arma or DayZ, as can be seen in the review I posted, but for GPU intensive games like BF it performs very well for the price. Also Intel generally have better single core performance which is normally better for running games, as most games are not optimised for using a lot of cores. AMD tends to perform better at multitasking a lot of small processes or for editing and rendering.
