At th moment, i would personally go with the Nehalem for video editing, thats the only reason I have at the moment. The extra CPU power isn't very useful in gaming until you start getting CPU bottle necks, something that probably won't be happening in this particular build.
I would recommend an E5xxx, E7xxx, or E8xxx simply because dual cores are great performance wise and price wise if you want to save money, OTHERWISE if you are willing to blow off ≈ $3000, you may as well skip core 2 quad and jump to nehalem...
@DaMak420, thats almost the same thing I posted earlier, without the core i7 extreme. Core 2 -> nehalem will get a *bit* of performance, but Core i 920 -> extreme is not so great, though its a dream build. BTW you put a link to the E7200?? HINT, you could almost buy a 1TB drive wth $100 these days.

Piggah is the one who will ultimatly decide. So, please do decide and tell us. The main decisions (the most intense arguments) are:
Do you want a Core i7 CPU or a Core 2 Duo CPU?
Do you want a dual GPU triple GPU or quadruple GPU solution?
Do you want to overclock and push your system?
Large computer case (full tower) or slightly bigger than the standard cases that you buy from brands like Dell, HP, Emachine...(mid tower)?
Some things we should all agree on and have little trouble deciding are:
WD 300gb velociraptor, Optional storage drive.
PSU, either Corsair 620W to 1000W depending on the GPU.
The Motherboard should come easily once he has made his decision(s).
The sound card I still say Auzentech Prelude, great card.
