Motherboard Recommendation for an Intel Quad Core CPU

[fibres]

Hi all

I am relatively new to linuxmce and am having a general good time with it except for the fact that I am having major prolems with mythtv freeziong. I am coming to the conclusin that it could be due to the motherboard im using. CVan anyone suggest a good motherboard to use with the new Intel Quad core processors, prefferably with as many pci cards as possible.

Regards
