Hi Guys

Running two GTX 980 in SLI on 6700k @ stock 4.0Ghz

I have a very well cooled case, and the GPUs are both on water cool blocks, so not loud and not hot.

Just for sake of looking to upgrade, I really can't find any really good FPS benchmarks in comparison of 1 x 1080 ti versus 2 x 980's (not ti) that show if it's worth it. I know I can recuperate some of the price of selling both cards (with the closed loop water blocks + fans) but not all of it.

Is it worth looking at? Anyone seen a clear comparison?

Thanks for the help.

Sure its nice, but not really necessary, and no I was referring to another commenter saying that you are probably only using one card, that's not how SLI works. For the most part, they more or less take turns rendering frames, so both are being used equally but there is still a limit to it's usefulness, and that is in cases where SLI does not work.

I would say only upgrade if you are unhappy with your current performance.

For example. I had a standard 2560x1440 60Hz monitor and a 1080, the 1080 was blowing EVERYTHING away, I was even able to play BF1 on Ultra at 125% render scale at 60Hz, I then upgraded to a 3440x1440 100Hz monitor and then the 1080 was having a little trouble running a few games, nothing terrible (BF1 had to be set...
well considering a single 980 is comparable in power to a 1060 6gb, I would say it would be a good upgrade. so little programs actually use the Sli processed for anything, I would venture 85% of the time your only using single 980 in games and such anyways.

 


980 SLI would be slightly behind against 1080 ti.
 


Yes - understood, and thanks. But I'm looking for something measurable and comparable.

 
1) That's not how SLI works, you can't only use a single card and the other takes overflow... no...
2) A single 980 is still a little bit more powerful than a 1060 6GB
3) FPS benchmark wise 980 SLI outperforms even a 1080 in many cases, even if barely.
4) SLI is a pain in the butt, but if you wanted to go to a single card solution, a 1080 Ti would be the only way to go
5) You won't get that much more performance, like 20-30% in most cases. But still a decent increase, and gets rid of SLI, which is a huge plus in my book.


I went from a 1080 to a 1080 Ti last week so I know what the performance increase is.
 


Hmm, it might not be worth the bother for 20 - 30%. Perhaps I should wait... But I don't stand to lose too much $$ if I do it now as 980 prices are dropping...

Not sure what you're saying by that's not how SLI works. I didn't make a claim as to how it does did I? But certainly I can see a nice advantage for going up from 4gb up to 11gb, surely? Since both my 980's are 4gb units.

So I went from a 1080 to a 1080 Ti just barely more of a jump from 980 SLI to a single 1080 Ti. But now I can run BF1 on Ultra 100% render scale.

Yeah - I am reasonably happy. Just trying to see what I could do to tweak!
 


Yeah its a relatively small upgrade. Only reason I did was because I wasn't happy with my 1080's performance. You should be good through the end of the year at least I would say. Only upgrade once the technology becomes advanced enough to where you are unhappy with your cards performance.
