Hello everyone!

I have tried to do some research but it hasn't been enough for me so asking help from here. I'm currently planning on building a new system. I mostly play games but in addition I like to maybe keep a stream open or doing something else for example simcrafting for WoW. In the future I also might have to use autocad.

I waited for Coffee Lake to come out even though it seems perfect for me I still have some questions.

1. I currently have a 980Ti and I'm tempted to upgrade to a 1080Ti right away, but then again I hear Volta is coming out in early 2018. Should I upgrade to a 1080Ti or wait for Volta? I currently have a 1080p 144hz g-sync monitor but am planning to buy a new main monitor which will be an ultrawide 1440p with high refresh rate and g-sync.

2. I am worried about the low Pcie lane count on Coffee Lake. I might give SLI a go at some point. Should I go with a 1920x threadripper instead? I am worried (because I don't know better) that a 1080ti in sli or a volta top model gpu will saturate the the pcie lanes.

3. In the end I'm mostly looking for the best gaming performance with highest framerates possible.

The thing that worries me the most is the pcie lane saturation. I don't want it to be a limiting factor. Also the 1920x is compelling because of the amount of pcie lanes. I'm just worried how it will perform compared to the 8700K in 1440p. And I would like to have the cpu perform well on a while on this 1080p monitor before I get the 1440p ultrawide.

Sorry for the long and maybe even a confusing text but I'm just stuck in my build atm because of these questions.

1. 980ti is still a good card. I suggest you buy your new monitor first and see how you do.
No doubt, in the future, there will be stronger cards available than the GTX1080ti.
But if you wait for the next best thing, you will wait forever.

2. Do not worry about pcie lane count.
With a single card, you will operate at X16. With sli, each will operate at X8. X8 is only marginally slower for a top end card. Perhaps 1%
Past that, sli brings it's own issues of screen tearing, stuttering, and non support in some games. A single strong car is always better if it can do the job.

3. Today, the i7-8700K is the strongest gaming processor available.
It will have the highest single thread performance around, and more than enough...

An 8700K will give you the highest frame rates. SLI is not usually worth the hassle because you may or may not be able to find an SLI profile for the game you are playing, so PCIe count isn't an issue. Your 980ti should be fine for now, but if you just have money burning a hole in your pocket, get the 1080ti.

Simple question - is your 980ti enough for your monitor right now? If it is, there's not much sense to get new GPU now, and then new monitor in the future. Your best move in this case would be to get new monitor and new GPU at the same time. On the other hand, if you find your current card lacking, it's ok to upgrade to 1080ti now, as it should be good for 1440p too.
As for 8th gen or 1920x - I'll agree with kanewolf, no need to worry about SLI.

You may have a hard time finding one quickly.

Threadripper is no competitor for gaming.

Thanks for the help guys, really appreciated.

Do you think the Volta GPUs are going to be even close to saturating a pcie 3.0 x16 lane? Just curious.
And this is a bit off topic considering my first post but does anyone have a recommendation for an AIO. I'm considering a 360mm or even a 420mm. I have been eyeing on the arctic cooling freezer 360 and alphacool eisbaer 420. All of my previous systems have been cooled with air before and I'm not ready for the custom loop hassle at least not yet. Suggestions if you have any are apperciated as well.

We are not yet saturating pcie 2.0 so I doubt any upcoming graphics card will have any problem at all with 3.0. Might even be less since smaller technology can keep more on the card itself and not need pcie data transfers.

If you have a decent cooling case, there is no need for an AIO cooler.
By decent case, I mean at least two 120/140mm front intake fans, preferably with a washable filter.
Here is a reference from Noctua as to which of their coolers would be appropriate.
http://noctua.at/en/tdp-guide

My canned rant on liquid cooling:
------------------------start of rant-------------------
You buy a liquid cooler to be able to extract an extra multiplier or two out of your OC.
How much do you really need?
I do not much like all in one liquid coolers when a good air cooler like a Noctua or phanteks can do the job just as well.
A liquid cooler will be expensive, noisy, less reliable, and will not cool any better
in a well ventilated case.
Liquid cooling is really air cooling, it just puts the heat exchange in a different place.
The orientation of the radiator will cause a problem.
If you orient it to take in cool air from the outside, you will cool the cpu better, but the hot air then circulates inside the case heating up the graphics card and motherboard.
If you orient it to exhaust(which I think is better) , then your cpu cooling will be less effective because it uses pre heated case air.
And... I have read too many tales of woe when a liquid cooler leaks.
google "H100 leak"
I would support an AIO cooler only in a space restricted case.
-----------------------end of rant--------------------------

Your pc will be quieter, more reliable, and will be cooled equally well with a decent air cooler.
