Hi guys!
I am looking for a CPU with the fastest possible single core performance and fast speeds. I pair it with a Titan X Pascal. This PC rig its just gonna be for gaming / simulation uses. The game that I will play the most is Prepar3d that is a professional flight simulator. I will show you the processors that I have in mind: 6700k, 4790k, 6850k, 5960x, 6900k

The single core performance under single thread is likely 6700k, but it's just few % faster than 6850k or 6900k. It's about 6-7% faster than 4790k. But if you are pairing that with a Titan X, consider to get a processor with 6 or more cores because many games and application will use more than 6 cores in the coming years.
By the way, the rumor has it that a cut down version of Titan X Pascal will be released soon. It is likely named 1080 Ti and will be priced at least $400 dollar cheaper than Titan X. You might want to wait just a little longer.

I'll believe it when I see it. Multi core processors have been around for a very long time, and we have been hearing this forever. AMD bet the farm on it, and lost.

I personally would not bet on it. Games are generally a linear load, there is not a whole ton to be gained in MOST games by spreading it over multiple cores.

The latest Intel architecture will be capable of the highest single-threaded performance. The 4790K and 5960X are both 4-generation "Haswell", the 6850K and 6900K are both 5th generation "Broadwell", and the 6700K alone of those you listed is 6th generation "Skylake".

If you're fine with only 2 cores, you could get away with using the $60-70 Pentium G3258. It's a 4th generation CPU, so its per-clock performance is slightly lower, but with a lucky chip you can get 90-95% of the performance of an overclocked 6700K's single-threaded performance for 1/4 the price. Otherwise, as Rogue Leader has said, the 6700K is your best bet.

Most new high-budget games out today benefit from more cores and threads, even if they still have a main thread that relies on single-threaded performance. It's not uncommon to see lower-clocked 6-core / 12 thread CPUs outperforming quad i7's.

Take a look at how Dues Ex: Mankind Devided can distribute load, for instance:

Doom runs (marginally) better on a Sandy Bridge 6-core than a Haswell quad:

The same with Mirror's Edge: Catalyst and Total War:

Even Blizzard's latest title can use 8 cores, even if CPU scaling ceases once you get to ~i5 levels:

MERGED QUESTION
Question from AndreDBU : "Single Core or multi Core? 6900k vs 6700k"







Hello,

Although I do no personally use P3D, a close relative of mine does use it a lot.
For the CPU, I would recommend the I7 6700K, the successor to the I7 4790k. The reason for this, over the much more expensive processors such as the 6900K, 6950X, 5960X etc etc etc is that is has a high Single core performance. In programs like P3D, and other similar programs, fewer, faster cores are better, this being due to the programs not being able to utilise more than a certain amount of cores, so the rest just sit there doing very little.

For graphics cards, from what I can see about the program, SLI doesn't work that flawlessly. Even in programs where it does, I wouldn't personally recommend it. It has it's own issues such as higher latency and some programs not properly supporting dual graphics cards can even see a decrease in performance.

My hexcore AMD 1090T phenom 2 chip, overclocked to 4.4ghz per core, was beaten hands down by my i5 quad core 4790k, even at only stock 4ghz speed, for p3d.

Don't listen to anyone who says 'more cores are better' for p3d. Other games, maybe, I wouldn't know. But, just so you know, I got rid of my 1090T hexcore, and kept my i5 4790k, which happily overclocks to 4.6ghz, and walked all over the AMD hexcore all day, in every application I used.... my 4790k and single gtx 1080 runs p3d no worries.... very smooth and looks amazing.
