Types of i7 computers

I might be mistaken but is the i7 8xx series the new chip form (1156?) and need same MB as the i5.

Correct, the i7 870 is a socket 1156 chip and requires a P55 series motherboard.

I would never over clock, in fact I underclock my memory by setting it to 2T. Of course tons of people overclock but I am not in favor of it.

Ya 920 is best for buck no doubt. Others are waste of money.

Just go for more and more ram instead of overclocking.

And it is also a dual channel architecture which limits you to 16GB RAM and most boards only have 4x DIMM slots which means you are almost capped at 8GB at the moment as 4GB DIMMs are not readily available.
