I ran my old machine also from 2010 till this year on 8gb. Also for gaming the 2010 i7 was quite fine. The only bottleneck was the VRAM where we somehow went from 1GB being perfectly suitable to 4GB being barely enough. Meanwhile old games sometimes look better than modern games, because they actually put effort into optimizing the graphics.
i love it when the “this program is keeping the computer from shutting down” program is the shutting down program
