Well, here's a build with enough RAM for editing and a strong CPU for some heavy programs. Also a great gpu for gaming, with lots of CUDA cores (if any of your programs can utilize those). I've left enough headroom for any OS you might want to buy, but if you already have the OS, then you should add a "Noctua NH-D14" cpu cooler

EDIT: if you think you're not going to need the GTX 770, then please tell me, so i can try fitting some even beefier CPU's in this budget (though it's likely not possible).
EDIT2: Here's a i7-4930K CPU crammed down to almost fit within your budget ($1350):

Would be faster when editing but quite a bit slower (still faster than a 650 ti boost) in games.
