I know this question has been asked many times but I am yet to find a clear answer.

I've recently done a system upgrade to Kabylake from a first gen i7 (bloomfield overclocked to 3.6ghz) with the intention to play games at 4k. I'm now wondering whether i've shot myself in the foot going down the kaby lake route as I'm now thinking of getting a second 1080 ti for future proofing.

Only issue is i'll be on 8 lanes per graphics card and a 860 watt PSU.

If I did buy another 1080 ti would i be wasting my money with the kaby lake setup? I didn't want to go down the 6 core route as I don't do anything else but gaming on this rig, so seemed like a waste of money for it's intended purposes.

I just purchased the following:
- MSI Nvidia GTX 1080Ti Founders Edition 11GB GDDR5X Graphics Card
- Intel Core I7-7700K 4.20 GHz Socket 1151 8MB Cache (overclocked to 4.8ghz)
- Asus Intel ROG MAXIMUS IX CODE LGA 1151 ATX Motherboard
- Corsair Dominator Platinum Series 32GB (2 x 16GB) DDR4 DRAM 3000MHz C15 Memory Kit
- Corsair Hydro Series H100i v2 Extreme Performance Liquid CPU Cooler
- Corsair AXi 860W Fully Modular 80+ Platinum Power Supply
- Corsair Sp120 Rgb Fan - With Controller
- 850Evo Pro SSD

Thanks :)

Yep fine.

What are you throwing at the system that it can't handle? Just curious as to why you need a second Ti?

At the moment it can handle everything. I'm just thinking about future games as I want the system to last me a few years before upgrade. I guess volta will be here soon anyways. Im not anticipating Vega will make much of a splash in terms of competing with Ti, at least based on Ryzens performance

Ok cool - the reason i asked was because SLi when it works is great, but it often doesn't work, in terms of games supporting it etc. I've had SLI a few times now, mostly recently 2x Maxwell Titan X's and it was "OK" - pain in the arse when upgrading the drivers!

Single card is always regarded as a 'cleaner' solution so if your PC is currently handling everything, just enjoy it and upgrade further down the line.

Yep that's why I originally waited and went down the kaby lake route with a single 1080ti.

I've had the old dual gpu cards before from nvidia and ati and I remember even having problems with those.

I guess if a 700quid card can't handle 60fps 4K I don't see why I should give nvidia another 700 quid for 50% more performance :)

I'll just upgrade to Volta when it comes out then :)

Thanks for your help
 
I'd be tempted to just hang on and see what happens to intel pricing and the x299 platform announcements. For now you've got a great chip for the single card, have to be honest my 1080s in SLI are reasonably heavily clocked and my 6700k struggles to keep up so maybe see what the next 6 months brings with Volta/Ryzen and its effect on intel/nvidia.

Let's not forget the 1080s lost about £100 on price within 3-4 months so no rush really ey mate.
 
waste of time and money :D

I'm wondering why people invest in 6-core processors and SLI configurations when it's obviously a waste of money for gaming. I have the cash to burn too but i'm not that stupid :) I'd rather get whats sensible and give the rest to charity
 
Well sli is great when it works, which is less and less often from what i hear.

Far better keeping the cash to one side for when the next latest and greatest single card comes out :)

6/8 core cpus may not give you much extra for gaming at the moment, but that may well change in the future....
 
I just built almost the exactly the same system. And i can tell you SLI works great.
If you want me to test a game (thats if i have it) let me know :)
