cungquan :
one more question, what if i take the ryzen 5 1600, does it make a lot different ?
cungquan,
If the budget can include the i7-6800K and X99 motherboard, that would be a superb combination. X99 consistently produces very good CPU performance. I much prefer LGA2011-3 to LGA1151 or AM4 as LGA2011-3 will support 40 PCIe lanes instead of the 16 of LGA1151 or 20 of AM4 and has quad channel memory and a much wider memory bandwidth. SYNPHUL wisely used 4X 4GB in the recommended system which completes one memory channel and that leaves slots to add another 16GB. Today, I consider 32GB necessary for a workstation. I use an HP z420 with 32GB of RAM and it would not run a VRAY 3180 X 2160 rendering of a large project. I transferred it to the office z620 that has 64GB and found that the rendering during setup needed 37.1GB of RAM, then settled back to using 18.7GB. That also ran all 16 cores of the z620 at 100% so I am also looking at GPU rendering for the first time! We are currently replacing the z420 with another HP z620 > E5-1680 v2 8-core@ 3.0 /3.8GHz, (which will run at 4.3GHz on all cores) /Quadro P2000/ and
64GB of RAM.
In this use, unless you are using programs that are well-distributed across multiple cores, a 6-core is a very good compromise. 3D modeling is extremely single-threaded- running one one core and the more cores, the lower the single-thread speed. This is so important, that users of Solidworks- which has the most well-distributed best
CPU rendering are now running i7-7700K 4-core systems overclocked to 4.7-4.8GHz and as I've done, rendered on dual Xeon systems with many cores. In reaction to this trend, Solidworks has introduced
Visualize which is GPU rendering. When our new system is ready,
Visualize will have a trial.
So, if the i7-6800K X99 system is possible and with the Quadro P2000 that would be a very good system and overall have a better potential for expansion. If you added a second P2000, providing two GPU's and 10GB of memory, the results are said to surpass! the performance of the average Quadro P5000 16GB - up to a point in file size. The P5000 average Passmark 3D=
10575 but can run up to
14373.
> Keep in mind that LGA2011-3 is ending in the Autumn- 4-5 months, to be replaced by LGA2066.

OPTION:
Not to throw a wrench in the works, but on a budget, it's possible to have very good performance with very high reliability- and quiet running- by buying a used workstation.
HP Z420 WORKSTATION E5-1650V2 3.50GHZ 24GB No HDD Two Nvidia NVS 315 No OS > $499
In reasonable condition and has 24GB of RAM. This uses one of the best LGA2011 Xeons ever, the E5-1650 v2 6-core Xeon @ 3.5 / 3.9GHzA friend has a z420 with an E5-1650 v2 and he is running it on all cores at 4.3GHz, so that would not give up speed to the i7-6800K. Add a 250GB Samsung 850 Evo- $100, WD Blue 1TB- $50, and P2000 -$450 = $1100 (+ $45 shipping). The two Nvidia NVS 315 GPU's in that system are worth about $60 each, so the net cost could be near the $1,000 target.
These workstations have OEM windows 7 Professional 64-bit so you don't have to buy the OS as you would when building- saving $140. HP can send you a restore disk and when loading the HP Windows, it will automatically activate. The very good part of this option is that you don't have to order, assemble, wire, and configure it. I also like to use ECC RAM in a system used for rendering or simulation. These are extremely quiet-running.
Yes, obsolete technology, but 4GHz is 4Ghz
