Do not go higher than 2.6 ghz for the Cpu unless you want to destroy your laptop or you have water cooling or are running nitro & know what you are doing. The nvidia 320m Graphics card Shader clock must not go higher than 1400 mhz - as this is the main factor for higher framerates anything higher will cause a crash or Gpu lock down (my settings are 580/820/1400)The Gpu clock must not go beyond 600 mhz(but not recommended I say leave at 580 higher than this = hotter) & memory clock - leave at 820mhz.
The Bottom line is the Asus k5oid x1 should have had a 2.4ghz Core2duo with a slightly faster Nvidia 330m Graphics Card , however if you don't mind tweaking and tinkering around the system you can squeeze out every last bit from the k50id x1 - see my game testing benchmark results and you can always upgrade even the graphics card to a 360m GT - still looking into that, but possible.
