I would still go with Intel for AutoCAD and Revit (single core performance) https://www.tomshw.de/3d-workstation-benchmarks/ https://www.pugetsystems.com/labs/articles/Revit-2018-Coffee-Lake-CPU-Comparison-1052/ You need to decide how much RAM and SSD space you need. I would take a board with four RAM slots, so that you can upgrade to 32GB later if you go with 16GB now (RAM is still quite expensive at the moment, so if you don't need it now...) Here are four options with i5 8600K and i7 8700 - and SSD with 250GB and 500GB. I think a GTX 1050 TI 4GB is enough for Acad and Revit. It's the biggest GTX you can get with a passive cooler.

System specs? Assuming that you're using Win10, it could be related to the "fast start-up" setting... But it could also be something totally different, as Francisco said. More info is needed.

You can take basically any PCIe x4 M.2 adapter card (M.2 2280). For data only you just have to make sure that there are enough free PCIe lanes to get the full speed and install the NVMe driver for windows - as far as i know only needed for Windows 7, Win 8 and 10 should already have NVMe support. If you want to boot from it then this could be a problem, because your UEFI/BIOS needs to support NVMe... and it doesn't look like there are any recent updates available for your board. The lastest one is Version 4801 Beta Version from 2014/07/28 https://www.asus.com/Motherboards/P9X79/HelpDesk_BIOS/ I think the only thing you can do is to look for a modded BIOS or mod it yourself... https://www.win-raid.com/t871f50-Guide-How-to-get-full-NVMe-support-for-all-Systems-with-an-AMI-UEFI-BIOS.html (edit: I have to add that i don't know anything about this forum and the quality of the info in this thread. And i never modded a BIOS myself. This one just came up in the search for "NVMe mod BIOS" and looked quite solid to me at first sight. If you're interested, you should do your own research... ;-) )

I don't know about your timeframe, but if possible i would wait a few weeks or even months to see what the outcome of Spectre and Meltdown will be. A few days ago i thought, better buy AMD, but now it seems that they are affected more than they said (at least by Spectre).

What about the .bak and the autosave file?

maybe archdaily.com ?

Mixing RAM normally is not a good idea, especially different sizes/models. It can work, but there is no guaranty. If you already have it, just try it (arranging them in pairs - look into the manual). If you need to buy new RAM you should try to buy the same 2x8GB again. But even if you get the same modules again, they can contain different chips and it's possible that they don't work together. I had this problem when i was upgrading from 4x 8GB to 8x 8GB (on x99) so maybe a bit more critical with 8x8GB and maybe a bit more vdimm could have fixed it, but i didn't have the time to experiment and ended up buying 4x16GB. Ok this was two years ago when RAM was cheap...

The vcore is ok, but like i said, i suppose that you could lower it because the auto overclocking tends to set higher values. But you have to test it. I just meant that the limit should be around 1.35-1.375v since you said that you would like to try the 4.5GHz. But the more important thing would be to check the vccsa (and vccio/vtt) as i said. https://rog.asus.com/forum/showthread.php?19926-3930K-C2-Degradation

1.3v is already quite high for 4.2GHz. Should be working with less vcore if you set it manually. I wouldn't go above 1.35-1.375v. But the more critical voltage is the vccsa. High vccsa can quickly damage the CPU. There were several reports of destroyed Sandy Bridge-E allegedly caused by too high vccsa. You should keep it below 1.15v to be save. I don't know if this had been fixed, but there was a problem with auto overclocking setting too high vccsa. 4.2GHz is normally easy to achieve. The "wall" should come around 4.4-4.6GHz on most 3930K air cooled. The temp is ok. I would try to keep it under 70-75°C, maybe 80-85°C on hot days. A fan for the MOSFETs could be helpful (to improve stability and to keep the board safe). It's more relevant if you use water cooling, but i had one dead X79 board (burnt MOSFET) with an air cooled 3930K (4.6 or 4.7GHz).

Yes, i've seen it. Very interesting development... 18 instead of 12 cores for $2000 :-) I hope there will be a way to overclock AMDs dual CPU platform... ;-) http://www.anandtech.com/show/11464/intel-announces-skylakex-bringing-18core-hcc-silicon-to-consumers-for-1999

I would wait for the release of the upcoming Ryzen R9 (Threadripper, up to 16 cores ) and Core i9 (Skylake-X , up to 12 cores). There should be press releases on Computex next week.

Nikolaos, yes the numbers are very inconsistent. I would also think that this could be a driver issue. And the Pascal based Quadros are still missing. I would also say that a GTX should be enough. But i think the main question is the budget for this build...

I would say definitely the 7700 for CAD. Much higher single core performance and better efficiency (energy consumption, heat, noise) and the X5670 is almost 7 years old tech without support for current standards like M.2 SSDs or even enough SATA3 and USB3 ports. And it is a used system with aged components (PSU, board, fans). If it is only for CAD and you're on a budget i think you could go for an i5 instead of the i7. The 7600K has almost the same or even better single thread performance and is a bit cheaper. The "problem" at the moment is the high RAM and SSD prices.
