can someone tell me if my spec can run rpcs3

hi i was hoping before i spend anymore time someone could take a look at my specs and tell me if id be able run hard corps contra, scott pilgrim, and dragons crown. im able to run games like sfv and mortal x dolphin and other emus but i cant get more than 22 fps on hard corps and scott pilgrim is worse. also fyi i can only use builds that allow 2 core use. so here are my specs somebody please let me know if im wasting my time and if not which build will run these games. Thanks!!
