New 4K gaming rig. Need recommended build help

Need recommended assistance on a build for 4K gaming. Already have a 4K monitor with gsync provided from a friend that works at Asus. Replacing an older gaming system to a new one that supports 4K gaming. Can consider SLI but would like to avoid if possible due to bad gaming experiences with SLI in past unless this has changed.


Budget:
Under $3500

Expectations:
4K gaming

Usage:
Only gaming and watching streams and videos. 95% gaming

Current played titles are Fallout 4 w/ mods, Witcher 3 w/ mods, World of Warships, World of Warcraft, The Division, War Thunder, GTA 5 online

Upcoming titles will purchase: Battlefield 1

While I play MMO, millitary sims, and RPG's mostly I do play FPS titles but not as much.

something like the above.

SLI is still a problem for some titles.   I don't have any specifics, since I don't sli.   I don't think much has changed.

As fas as overclocking, with Skylakes multi-core enhancement, the Turbo speed, 4.2 with the 6700k, is across all four cores. In the past, Turbo was single core with the other cores getting less speed as they came into play.

The added stage 1 overclock would be to get to 4.4, hopefully, and to keep the core speeds up longer.   Multi core enhancement, I believe, does toggle the speed as needed instead of on most of the time under load.

G-sync just helps with tearing -- when the screen buffer gets caught between two frames and part of the displayed screen is one frame and the other part is another.

AA helps with the sharpness of edges being rendered and make them look more realistic. Higher resolutions diminish this effect a little bit. Super-resolution, where the scene is rendered at 4x the resolution of the screen and down-sampled, helps with this effect as well, but if you're at 4K/UHD already, you're not going to be running super-res to render the screen at 8K.

The upcoming Pascal Titan should be able to do single card 4K/UHD very well and be cheaper than dual 1080's.

You are not gonna have smooth gaming at 4k with one card tho:









If you still don't want to go sli then I would wait for the titan

nothing's really changed with SLI.  these new consumer Pascal cards have high bandwidth bridges, but what is really needed is a completely new interface.  NVLink is only for super computing, but it was hoped that it would find its way to consumers as well...perhaps in the future.  PCIe 4.0 (with a new connector) is supposedly on its way as well (to be finalized in 2017), but when we actually see products is anyone's guess.     

From what I have seen sli 1070 is about 10fps slower then sli 1080.

so for example a 74fsp vs 64 fps, now that I saw in one game only but in most its more like 84fps vs 74fps so I think sli 1070 will due, just keep in mind you are right on the line which means you are gonna be short within a year or so with newer titles.

Well then 1070 for sure that is a no brainer, but personally I recommend upgrading every 2 years if the need is there. aka go sli 1080 now and upgrade in a couple of years or so, which is when you should need more gpu power.

That way you get the most and best out of your money.

both pro and evo will be fine, they are around the same speeds as far your use goes, but ya writes are faster. the m.2 is in a different league.

as for 950 needed or not, need no, but as mentioned if you want speed then that is it.

sli 970 can't do what sli 1070 does in 4k

Glad to hear that its 1070 you will love that

Its upto you, I personally trust the pcb from evga, I find their products to have better quality.

Nice monitor
