Hey there, I was briefly checking through your conversation with the last tech,
I'd suggest taking a peek at this discussion here:
for the purposes of video editing, GTX vs Quadro, save your wallet and go GTX (like a 980 OC by EVGA)
For modeling, animation and rendering, you would be winning more with a Quadro series, however, if budget is a concern, to truly get the most out of your money, I'd still consider a GTX 980 OC at the LEAST. by EVGA, it may not match up but you can afford the other specs...
For a processor, I'd recommend taking a peek here, this is almost a matter of preference
Truly, for your budget, you'll want to go with a GTX series card and an i7 series processor, but if you can stretch your budget, go with a Quadro and Xeon setup to suit your goals.
hope that helps
