Unfortunately, playing at 1920x1080 (1080p) will require overclocking (both GPU and CPU) for some games right now with that setup. In the future, even more will require it. My setup is nearly identical, and I already wish I had gone with a mainboard that can do SLI so I could boost it with another overclocked 570.
Note: Uther39 was right about your power supply -- you really do need a better one for that system. Cooler Master GX series aren't that good. You need something like a Corsair, XFX, SeaSonic, Antec, or SilverStone. I recommend a single +12v rail version in the 650-750W range.
