Speaking from past experience, I agree. Always save your money and go for a strong single GPU instead, you will get a lot more performance for your money as well as less power usage as well. It's a win win

Considering that most games don't support multiple cards it would br wise to stick with a single card i.e. 1080ti

It's almost never viable to just buy another similar card later on. For example, I could buy a 2nd hand 970 for 150€... Or sell mine for 150€, buy a 1070 for ~420€ new and have a better setup across the board, without the need for a beefier PSU.
I've done the "buy 2nd card later" route, but it only made sense since I had to RMA the card, and received a card which was a generation newer. Even then it wasn't ideal, little issues become annoying over time.
But as an answer to your question, PCI-E 3.0 8x is plenty. There's a measurable, but not really noticable impact.

It's not worth it at any time unless support is spot on, which it isn't. With DX11 *most* of the larger software houses had at one point supported dual GPU so you usually got a patch after launch that made it work. AMD can not make it work after the fact. Roy Wood said this recently.
When we switched to DX12 it changed from how it worked in the past to two new ways of doing it. Explicit and another one. However, only one or maybe two games that have launched with DX12 have actually used it (Forza was one but it took about four months). IIRC ROTTR has it too, but again it's not very good.
Because of that and stupid fast GPUS like the 1080 and 1080Ti game devs have simply stopped using it completely. 4k is a crock, most are still using 1440p or less so I guess they see it as "Well our target audience has enough GPU power, why bother wasting time and money on something that won't be used?"
Now AMD have staked their neck on a chopping block for their next GPU tech. So have Nvidia, actually (not Volta, the one coming after) and that is basically multiple small cheap dies (like Polaris) on one bigger die. So for example a dual core GPU, or if you are loaded a quad core GPU and so on. This means that at some point in time AMD are going to have to get Navi into a console so that *everyone* codes for it at the metal so to speak. When they do that? their big plan will be complete.
Until then? 2 million foot pole with a condom on the end. Crossfire is just complete and total fail. Even when it does "work" the texture flicker and stutter are still very apparent.
I crossfired a pair of Fury X and realised that the good old days were gone (such as my 7990 which was awesome). It's just been dropped like a lead balloon.

Thank you for your opinion. Greatly appreciated.

Thank you for taking the time in giving me your opinion on this subject. Greatly appreciated.
I use to run two EVGA GTX-580 Hydro Copper in SLI on my older z68. It played all intensive titles like the original Metro since 2011 with everything turned up in Ultra Settings including vertical sync without any tearing. Now I was using a 1929x1200 60hz monitor too. I've had a few BSOD's. Probably due to video cards bottlenecks on some games. Though everything was fine until my Antec HCP-1200 needed replaced under it's warranty. Antec didn't make that model anymore so gave me a brand new HCP-1300 Platinum. Unfortunately, it was faulty and fried my dual video cards and motherboard. Thank GOD I had all my computer parts under extended warranties. I got exactly what I paid for my motherboard, sold my i7-2600k for $100 less then what I paid for it, it wasn't damaged and EVGA sent me two brand new 980 Hydro Coppers for free since my 580's were still under the extended warranty. I know use the Corsair RM850i. 10 year warranty and still doing well.
I'll transfer my Corsair 850 into my new build since I have 9 more years on it. Looking to get the Asus z270 WS, Hero or Apex models with an EVGA 1080 TI Hydro Copper and a new monitor. Can't decide whether I want to go with a 1080p 240mhz or 1440p 144mhz OC to 165 mhz. I've been gaming on 1080p 60hz for over 6 years now and I think anything above a 1070 will bottleneck my cpu at 60hz. So I guess it's time to make the jump into a new monitor.
Now that I got my memory and video card questions taken care of, now I'll have to decide on which monitor resolution I should be aiming towards and I hope a single 1080 TI will not be over kill for a single monitor setup using either 1080p or 1440p.

Those were the glory days for multiple GPU in all honesty. I started out my endeavours with two 5770 Radeons in Crossfire and hated it. Then I found out that AMD had been basically lying and Crossfire was a bust. They did fix it after that though, which is why I got a 7990. But yeah, back in those days two GTX 460s gave the 480 a big slap for £150 less. GPU manus got greedy though, and removed the SLi bridges from cheaper cards etc. None of which helped multiple GPU.
I think it just never really took off. Apparently multiple GPU users were 1% of a 1% audience. We really were that small in numbers.

The difference in x16 and x8 is about 1% or 1-2fps. You will not see much of a difference.

Yeah, I remember my first computer custom build was the original Alienware ALX Aurora. 930 AMD processor, 2 cores. What a waste of money back then. $7,000.00. It had dual 6800 Ultras in it and one of the cards was dead. After shipping it back I paid an extra $100 and got two GTX 7800's. Lasted me for about 10 years until I replaced them with a 8800 Ultra GTX XFX. Then used it as a back up computer while building the z68. Now 3 builds later, I'm amazed how much cheaper it is to build a great system. And the efficiency of the new Pascal Cards that can be OC'd on air with lower temps is amazing. I'm still stuck in the ambient cooling world with my Koolance ERM-3K3UC cooler, purchased in 2011. I have over $2,100.00 invested in it and will never get even half of the price back if I try to sell it today. So I'm stuck in the liquid cooling world. Back then those 580's really needed cooled. When I get the new 1080 TI, I guess I'll be overclocking it to around 2000mhz+ since I have the cooling method available. I'll put a small overclock on my 7700k. Not going to push it past 4.7 ghz.
So any thoughts on the 1080p or 1440p monitors?

Reasons to SLI/Xfire:
1. Looks awesome
2. Folding PPD - if you have a top level card already 2 is better. I would assume it also applies to other non-gaming applications that use raw GPU power.
Reasons not to SLI/Xfire:
Pretty much everything else.
And no you won't notice the difference x8 or x16 unless in bench scores or the like.
