Once again, your machine may run these games at their lowest settings, but not well. The stronger CPU will help, but only marginally. You simply don't have the CPU/GPU/memory horsepower to power these demanding titles.
BTW, your message signature indicates you have a Intel Core i3 530 @ 2.93GHz, 8GB DDR3 SDRAM, 750GB system. It would do okay as long as you have a good GPU.
