Choosing a CPU for 3D Game Development and Testing

Long story made short, I need a processor that can handle both 3D rendering and animation as well as play demanding games at acceptable levels of detail. My budget for the entire build is $1400-$1500 at the most, but if I can do cheaper, that's a plus. Recommendations?

The Long Story Aforementioned
I've recently gotten into game design with UDK and found that a Core-i5 430M does not like 3D modeling. My Pentium E5300 with integrated graphics won't even run UDK without SwiftShader (and you can guess how fast that runs). The point is, it's time for an upgrade. Being a computer enthusiast, and seeking a computer that will make me feel all warm and happy inside for years to come, I have decided to jump right in and build one (after some serious research into how to go about it).

In terms of a processor, I have been unable to determine how much power I actually need. As the budget for this build is coming via parental generosity, I have to stay within a reasonable price range. In this case, that means a blurry line somewhere around $1400-$1500 at the high end. Within that price range, I need to buy a computer that can handle all my needs, including not just 3D modeling and lighting (which I understand benefit from multiple cores), but also actual gaming so I can play-test the levels I design (which I understand benefits primarily from clock speed). Most of the pages I have found while researching on the internet deal with just one or the other of these uses, but not both. Additionally, I have seen a lot of recommendations that a given processor is "better" than another for a given purpose, but not a lot of discussion on just how good a given processor is, or how much better than another. I don't want to be blowing $200 extra on something if the actual performance won't be noticeably better.

So what I'm really asking is this: which processors would you recommend for a gaming/3D modeling PC build, and why? I have sort of gravitated towards LGA2011, and maybe a 3930K or a 3960X, but is there really that much difference between the two? How much difference is there between either of those and the 3820? For that matter, is LGA2011 even a good idea in the first place?

And finally, are these even the right questions to be asking, or am I just revealing my ignorance?

Any help that anyone could give me on any of my numerous questions would be much appreciated. I've learned enough online to know a processor is central to the build and that it should be chosen first, so I'm basically stalled until I figure this stuff out.
My Exact Requirements:

* Autodesk Inventor ()
* Blender ()
* CorelDraw Suite X6 ()
* Unreal Development Kit ()
* UE4-Based Games ()

Minimum
* Blender ()
* CorelDraw Suite X4 (–)
* Unreal Development Kit ()

Not entirely sure yet. I hear that custom can be a bit of a hassle, especially for first-timers, but I enjoy a good challenge. The main thing that would stop me from going with custom would be cost; even if I go closed-loop, I'll want to ensure I can upgrade to custom later on.

I would go with atleast 16 Gigs of ram if not more. Also the fastest ram you can get.

The CPU I would go with a 3930K just because it seems to get the best bang for the buck. Yes it is around $500 and if your budget can not afford it you might want to look at an Ivy Bridge CPU like a 3770K. They run hot but if you are looking at liquid cooling then it should not be a problem.

As for the HDD go SSD, way faster but you will want a HDD too because SSD have a limit on the number of writes can be done to them so they are greate for OSs but not so much for files.

Is a 3960X for $700 less of a deal? How much difference would the 3MB of cache make, and do they overclock similarly?

WOW. that is a smoking deal. If you can get a 3960X for less than $1000 then get it and let me know too. :)

You only get a 20% (on average) performance improvment over the 3930K but at that price it is only a 29% difference in price making it well worth it.

You can get them at $692 in "Used - Like New" condition from Amazon. Well, at least you can right now. Maybe not after more people read this. I'm guessing its a bunch of people who upgraded to 6970X when it came out.

Yep probably. I only said that a 6930K was a better deal because with a 6970X you would only get a 20% improvment for 100% price but if you are talking used, I donot know what the price would be on an used 6930K would be. You would have to look at that price so that you are compairing apples to apples.

Just as a warning, be careful buying used CPUs because you never know what was done to them. They might have been used in some extrem over clocking rig.

Strictly speaking game art development, gpu is the most important part. Blender/max/maya/any 3d modeling software's viewports are single threaded. And it doesn't matter that they are because they are gpu dependent not cpu. Sculpting software like zbrush or mudbox is done on the cpu but because how it's calculated, it doesn't need high specs. Baking lightmaps is about the only reason why you would want a good cpu. But the ue4 demos did not even use lightmaps.

However your budget will limit you. Even going with a 3770k, you are topping out your budget.

Haswell will be out in June. Depending on when you need this, it may be worth it to wait.
