Zxeon,
For demanding workstation applications- and 3ds, video editing / processing, and rendering are among the most calculation intensive, consider an LGA2011 Xeon instead of LGA1150. There are important advantages in that an E5 Xeon has double the memory bandwidth of E3, there are almost twice as many PCIe lanes, there is typically more cache per core than E3, and most importantly, with LGA2011, you can use 4,6,8,10, and 12-core CPU's instead of limitation to 4 cores.
There is a line of LGA 2011 Xeon E5's, the E5-1600 series and these have excellent cost / performance qualities. the E5-1620 v2 is 3.7 / 3.9GHz with 10 MB cache.

It's not substantially more expensive than the E3 - at Superbiiz, $292 >

On Passmark CPU benchmarks, the e5-1620 v2 is ranked at No. 63 with a CPU score of 9450. For comparison, the Xeon E3-1231 v3 is No. 49 and 9762. However, as the E3 has a slower clock speed (3.4 / 3.8GHz as compared to 3.7 /3.9) with less cache (8MB compared to 10) and a much lower memory bandwidth of 25.6GB/s as compared to E5 at 59.7. Also, the E5-1620 v2 can run ECC RAM at 1866 whereas the E3-1231 v3 uses 1600 as it's top RAM speed. I don't recommend overclocked RAM for workstation use. I'm convinced that in real world applications the E5 with have much better performance. Plus, in a couple of years you could change to a six, eight, or ten core CPU and extend the life of the system. I have an E5-1620 system (not v2 @3.6 / 3.8GHz) but I use a dual quad core Xeon system (X5460 @ 3.15GHz for rendering. When I sell the Precision, I'll change the E5-1650 CPU to a six or eight core (the excellent six core E5-1650 v2 @ 3.5 / 3.9 about $585 for example) as rendering is a rare case of using all avaialable cores and even a sx core is a 50% increase.
You'll find that LGA2011 motherboards are more expensive than LGA1150. I recommend Supermicro and if you're a professional, you might even consider buying a dual CPU board and running a single E5-1600 and then getting a pair of E5-2600 series, something wonderful like the E5-2643 v2@ 3.5 / 3.8 and 25MB cache.
As for the GPU, take care, as Autodesk does not certify consumer /gaming cards for 3ds Max, only Quadro / Firepro:

A GTX will work, but for video editing and rendering, I suggest something with the widest bandwidth. The 760 is 256-bit- very good, but the 580 and 780 are 384-bit. When I used a GTX briefly- too many artifacts and crashes in rendering, it was a GTX 285 which was 512-bit.
Of course, things that are more expensive are often better, but I think going to an LGA2011 basis could add at least a couple of years use to your system and the cost per year will be less for a higher performance and expandability.
Here's a system I listed a few months ago:
