low end PC that depends on your spec, but i can suggest some of the game like Obcscure 1 & 2 (it can play with two sticks) , some old Call of Duty from COD 2, COD Modern Warfare, Call of duty Modern Warfare 2, Call of Duty Modern Warfare 3, Call of Duty Ghost, Bulletstorm (the old one not the new one)
for TPS style you can try Batman Arkham Asylum, Binary Domain, Darksiders, Assassins Creed 1 & 2, Inversion, Spec Ops The Line, Red Faction Guerilla
