True, but that is still the minority, and you can get some of them to work with a bit of tweaking (Farcry4). Also some do not support dualcores officially, but still work regardless. Even Dragon Age Inquisition, which was notorious for not running at all on dualcores, has been fixed, and runs acceptably well. Also, some games still have poor multithreading, and the Pentium@4,5Ghz should demolish any i3 in those cases, for very little money.
