What build would be best?

Nothing wrong with that set up...its right up there with the big boys! possibly a bit more hard drive since your into video editing/graphics rendering you may need the extra space...the WD 1T in SATA 6GT/s would be good. I don't see where others would think its "awful" unless there just looking at the "multithreading" which is avalible on the 2600K..not the 2500K Your choise of mother board is just as good if not better than the MSI board.
