The Xbitlabs guide will give you a LOT of information but I caution you to read through at least a couple of different guides and definitely download the datasheet. One thing I have noticed in some i7 920 guides, like xbitlabs, is they kind of mislead you as to the cpu temperature, they state you can run the processor up to 100c before the cpu throttles. While this is in fact true, it really should be stated that running above Intel's recommended spec (67.9c Tcase or low 70's core) is a very bad thing. This kind of thing leads people to believe the thermal spec of their 920 is 100c and believe me more than a few have stated this to me on various forums, that's why I try to get people to download the datasheet so they know.
