Hey, I'd say the ASUS P5B DELUXE, not vanilla, would be a great choice also. Its a very OC friendly mobo. I currently use it with a E66 and it is OC'd to 3200 with the HSF intel provides with the retail package. With a good hsf or water cooling, there are many people reaching above 3600 and 4000 effectively. Also has many bios updates, more than others mobo's I think?
