Advice for future proofed SLI rig

It's been probably 15 years since I've really paid attention to hardware and custom built a system. I'm now looking to replace an 8 year old Dell XPS system with a modern gaming rig. I mostly play racing games, and am hoping to create a system which would allow playing Forza Apex and Horizon 3 at 4K with ease. I'm also interested in other games like Titanfall 2 and Ashes of the Singularity in 4K if possible.

I'd also like to make sure whatever setup I get today, I'll be able to expand it in the future. I'm imagining a not too distant future with multiple 4K monitor setup for racing, which may require an SLI configuration. For that reason I'm assuming a larger PSU is needed. I chose an 850W.

I know next to nothing about overclocking and cooling - other than overclocking increases the temperature, of which there is a limit and point at which performance is not improved, and that cooling reduces the temperatures. But how do you determine how much of a cooling setup is required? Is the liquid cooling really only needed for overclocking? What are the typical noise levels of the cooling systems?

Below is the config I came up with. Advice/feedback would be appreciated.

Budget:
$3000

Expectations:
1440 to 4K gaming now, multiple 4K monitor gaming later

Usage:
Forza racing 4K gaming, occasional video editing

Special Needs:
Prefer to keep noise to a minimum

Can the graphics card, such as the 1080 EVGA ACX 3.0, really be overclocked much without water cooling?

That build looks right on.       Quality drives, psu, graphics card. If I was buying right now, it's thebuild I would have, with just the a Pro or A mobo and smaller HDD being my pick. Still would be on the fence for the CPU cooler.

No internal lighting ? Just me.

I've been debating the motherboard decision myself. Pro and A are cheaper than the Deluxe. All you really get with the Deluxe is built in wifi/Bluetooth, the extra USB ports, and some additional internal connection options. If you don't need those then don't spend the extra money.

Ok thanks for the feedback. I was just curious, but I can't imagine using any of the extra slots or any of the other features that come with Deluxe. I think liquid cooling also minimizes the need for extra heat-sink. I might splurge on a something like this in the future tho

Your setup looks really nice sidersdd, I hope the build will progress without a hitch. Mine moved to stage 6 yesterday so it's basically done, took them about 5 days to build it.
