First off I live in NZ parts are expensive because of shipping.
The Board is Dual Channel, ill probably look at getting 8GB (2x4) rather then getting a cheaper board (I like the clean look).
I would still go Ivy over Haswell, as from what I've been reading there is not much preformance for the price.
I looked into the 7950 w/boost and that is really interesting.
Problem is I would love a MSI motherboard but they are pretty hard to get here.
I am planning on crossfire (eventually).
I have not started editing yet as I cant on my laptop (its hopless) but as well as editing I'm a student who uses Arcmap, I'll look into the debate which is better.
