1080 Ti vs 1070 TI SLI...

[Gerr]

I caught a good deal on CL yesterday, two mint condition EVGA GTX 1070 TI FTW2(ICX) cards for $500.  Owner said they were used as graphical design GPU's during the day at his work and as mining at night for the past 8 months.  Never gamed on and only ever ran at stock speeds and no BIOS mods.  They looked brand new, not even any dust on the inside.  Both were tested as working and I am testing the first one for it's OC ability, and so far, at stock voltage, it's at +200Mhz on the core and +500Mhz on the memory via Afterburner for a sustained clock of 2050Mhz core and 9000Mhz memory and runs about 65* so far after a half hour of the Valley benchmark.  I hope the other one does just as well.  Once I get a HB SLI Bridge, I will try them in SLI mode, but probably will have to turn down the clocks a bit to keep temps in check, might even undervolt them a bit.

 

Anyways, on to the topic.  The 1070 Ti's are replacing a single MSI 1080 Ti that doesn't OC well, 1987Mhz max OC, which is currently in my main gaming PC(7700K@5.0Ghz - 32" 1440p@165Hz).  I am moving that card to my bedroom PC(6700K@4.7Ghz - 27" 1080p@144Hz) and it will replace a Zotax 1070 mini for high refresh gaming.  Before anyone says anything, I know, it's better to have a single card rather than SLI as not many games are optimized for SLI.  The way I figured it, if I play a game that isn't well optimized for SLI, I'll just play it on my bedroom PC with the 1080 Ti and use my main system for the games that are well or at least decently optimized for SLI.  Plus my main PC is a bit of a show-off rig, ie TG case with RGB, so having a pair of GPU's looks more "high-end" than a single GPU.  I know, I'm vain, and will accept less preformance at times for better looks, at least on that PC.  My bedroom PC is all business, ie preformance & silence, no looks, but gets the hand me down parts from my main rig as that's where my money goes.

 

What I want to know is if a game is well optimized for SLI, can I expect it to just match the preformance of my 1080 Ti or maybe beat it?  I have looked at various benchmark reviews and their numbers seem all over the place.

If you are not satisfied with your 1080 Ti then sell it and grab a 2080 Ti.

 

SLI 1070 Ti's will result in inferior performance and gaming quality than a single 1080 Ti across the board.

 

I don't have time to go looking for specific charts for you but SLI lately has been going just like Crossfire did here:

[Enderman]

Don't do SLI, sell the 1080ti and buy a 2080ti.

[Gerr]

What is done is done, just looking at what change in preformance I can expect.

[Fasauceome]

I've heard SLI scales with high resolution a lot better than high refresh rate, what's the performance target?

 

Also, a 1080ti at 1987, that's not exactly horrible, Pascal's soft limit is about 2GHz

I would recommend that you sell your 1070TIs for a profit and get a 2080ti.

I’d get a second 1080ti or get a 2080ti and hope it doesn’t crap out. 

 

A pair of cards will destroy a 1080ti. I know my 1080s are way better than my 1080ti was. Just hundered by a poor cpu. 

 

Bf1, bfv or bo4. I’d hope a 2080ti would be conparable to a pair of midrange cards though.

If you ever want to purchase a VR headset, don't do SLI.  The games that support SLI in VR can be counted on your hands. It's terrible.  Also, if you ever want to stream your PC to a TV it's not worth it either.  Games that don't have native SLI support can be forced, but it's a pain if your PC is in another room like mine is. (nvidia Shield)

Personally, I have had SLI since the 200 series and I'm itching to get away from it. I'm just sick of fussing.  Sure, when it works the power is great... but when it doesn't it sucks. 

Also, it makes upgrading kind of a pain in the ass to be honest...  Right now I have SLI 980's.  I may be nitpicking, but when I upgrade I want a single card that can outperform BOTH of them.  The only one really worth the hassle for a decent boost right now is the 2080Ti... and that's $1300!

@Princess Cadence BF5 doesn't support crossfire, and as far as I am aware there is no Crossfire Profile made for it either - I haven't checked in a couple months but nothing on google suggests there is support or a profile

 

The previous BF's did however, and scaled very well
