Well I dont think it will have mutch of a performance increase over a single chip unless I configure it diferently. For example If I set one chip to do only video encoding work and the other chip for everything else it will definitly have a performance advantage, at least I think so. The real reason to use dual chip mobo was because I wanted something diferent from everyone. Everyone uses old hardware (like me) on htpc's. And I have seen people use epia mobos etc. I decided to use diferent hardware. To be quite honest I have never seen a dual cpu htpc so that was enoguh reason to do so. And you guys are free to copy my right angled moldex mod. Just one question? Am I the first to do this? If so nic it acordingly. thanks guys, I am glad you guys are looking at my humble mod. P.S:if you have any questions or sugestions about anything that I do please post em and I will do my best to answer or concider the sugestion.
