The max Turbo Boost is 3.1 Ghz on one core, 3.0 with two cores. For a ULV CPU, that's not bad. You should be able to get most games running at a good stable FPS, but like cyrax33 said, there are soe demanding games that you probably won't be able to play.
If you ever have any issues, I recommend installing Windows in Boot camp.
