From what you said upgrading my mobo now would be pointless, but no I have not. For a normal ATX would full or mid be best?
I edited my previous post by the way. It may still be worthwhile upgrading. I suppose it is something to think about though.
The best i7 you can get if you was to upgrade your current motherboard now, and buy an i7 later would be the 3770K.
With the new motherboards the best you can get is a 4770k. The 4770k is better at stock speeds, however they do run hotter with overclocks, so if you intended to overclock the 3770k would probably be the best to go for now anyway. But depending when you do plan to get the i7, it might be worthwhile waiting, because if it is anywhere near May/June next year, newer i7's will be out.
With regards to your case, I would personally prefer as small of a case as possible. But I suppose you need to make that decision.
mATX you should be able to do, they have four expansion slots which is normally two graphics cards, but depending on how the expansion slots are laid out, and depending on the case, you may still be able to fit either a sound card or a wifi adapter. This will give you the smallest possible case.
ATX boards have seven expansion slots, but, again, depending on the case/motherboard layout it could potentially give you space for 8. Which will allow you to have two cards, one wifi adapter and one sound card and still have space for possibly 1/2 cards if you need it. But you will have a bigger case.
