If your a OC/gamer, and are pretty technicial. Get a DFI mobo. DFI are better at OC then Abit. I have the Abit AV8 3RD EYE. With Abits special Guru OC Utility. Its nothing great at all. Abit does OC their own way. This mobo is good for OC newbies.
The bad thing about these Abit Guru mobo's built for OC. Is that its pretty much made for OC through windows. This can invite windows corrution, and just harsh OC failures... Witch i have experienced them more then i can count.
I have a VIA chipset, havent had any problems with my XT.
