It is a great board, I am very happy with it and I have had way too many motherboards. I would say it would be a great board for a new overclocker simply because the uGuru software will let you overclock from within windows and it actually works, unlike most programs I have used, that way you can get some experience in that way before you mess around with your bios too much. The one thing I will caution you about is that it does allow you to set the voltages extremely high, so please read a lot and get some experience with everything so you don't fry anything.
Also remember every single component in your system needs to be very high quality to really acheive high clocks, and the reality is your not going to see some gigantic performance boost from overclocking, because your going to have decent stuff in your board anyway. I overclock all the time, but honestly it is more for the sake of doing it than anything else, when I am actually playing a game or something there is no discernible difference between my system overclocked or at the default settings, and there is always the chance of messing something up and ruining an expensive part.
That being said, I would be more than satisfied with this board whether I oc'ed it or not. I also would like to see Abit come back in the market so I am happy to support them when they put out a good product.
Your cpu is going to be your main determining factor in how high of an overclock you get, but this board certainly will take any cpu and let it reach it's limits.
Hope that helps 🙂
