I didn't know that the motherboards auto preset overclocks were so high , it's been my experience that those presets go up to 4.2ghz and yours goes uto 4.4ghz. If your at that speed and completely stable with a max temp of 60c then I wouldn't touch a thing and I would keep it right there. Yes you can go up to 4.8ghz or 4.9ghz but the performance gain that you will get in gaming will not be worth the effort. You may get an additional 5-10 fps but in the overall performance that wouldn't be enough to make it worth while. If going an addtional .5ghz meant that you could get 20-25 fps then something like that would be woth it.
If you would rather not enable the preset overclock and do it yourself you may end up with less voltage being added to the cpu and that would be a good thing. For now you can look at what the voltage is that the preset is giving the cpu and report back with that.
I would keep the cpu at the 4.4ghz if the preset is not giving the cpu too much voltage and then try to gain extra performance from the video card , that's where you'll see a bigger increase in fps if you overclock your video card.
