The Asus P35 or P32 chipsets are good models.
Maybe the XFX 680i or EVGA 680i as they are good too.
Abit are supposed to be good also but don't know much myself about Abit.
Im personally getting Asus, however the 1 Im getting is for overclocking and sli but they have many good boards not for those.
If you are getting the Q6600 and want to get the most out of it by overclocking it to 3ghz (you would need a better cooler than the stock) then the board I'm getting, the Asus P5N32-E SLI which is great for overclocking but it is SLI. There are simular boards that aren't SLI though.
