I'm looking for a pc build that runs assassin's creed rogue on mid/max, fifa 15 on max and cod on mid/high, but I don't want to spend a lot of money (at most 500). The best would be 300/400. I don't mind overclocking, so an intel pentium would do the job, but for graphic card, cooler (with overclock in mind) and power supply I'm not sure.
