Hello everyone
I have been searching about the latest in computer desktops, as I am planning to build my own rig for a coming project. My use of the machine is going to be basically focused on the analysis of fluid flow, and so, I will be using the machine to do a lot of Engineering CAD (Computer Aided Design), FEA (Finite Element Analysis), and above all CFD (Computational Fluid Dynamics), which is very CPU-intensive when involving gas flow.
I was about to order the parts of the build, and just before that I went across some news from different websites (including Toms Hardware) regarding a bug in the Skylake processors, which causes them to crash under heavy calculation tasks (involving prime numbers).

I have had some experience with intensive FEA tasks before, when i7 processors (1st or 2nd Gen, I am not sure) took an hour or a little more to finish calculating the results.
In this CFD task, I am expecting heavier calculations. I might even end up running simultaneous FEA & CFD tests. I thought about 4th Gen i7-4790K, as I did not find a lot of talk about such bugs in it, plus it gives comparable (or slightly better) single threaded performance, and added to that, I could find some discounted pre-built rigs, as system builders are trying to clear out their stock for the new Skylake builds.
Before the bug news, I considered i7-4790K for its price and performance, but leaned more towards the Skylake for better "future-proofing" (as some like to describe it), and the expected better support for Skylake with future technologies on the long term.
My question is, after the this news, is it worth to take the risk and rely on an i7-6700K in my case, especially that I cannot wait for the fix for long time (I can wait for a month max). Added to that the fact I do not quite trust BIOS fixes, as I did not have pleasant experience with Samsung and HP and their BIOS fixes for hardware issues.
Sorry for the long thread
Regards
