What difference will I see when running GTX 980Ti SLI.

post #1 of 10
Thread Starter 
Sorry for dumb question, I currently have a single gtx 980Ti. How much of an increase in preformance will I see if I buy a second GPU to run in SLI.

If your resolution is only 1080P stay with one. I have a Dell 3440x1440 with 2 980Ti's...................... and I don't notice much of a difference from one card to two. Many games are not even optimized for SLI Just Cause 3 for example.

If you plan to go up to 1440P or 4K then consider 2, if not............... you will not notice any difference at 1080P thumb.gif

I see nothing at all wrong with your system. I haven't played Overwatch, but I would guess either the game is not optimized yet, or drivers. Either way, the game probably doesn't have sli support yet either.

I get 110fps average in Overwatch on a Titan X @ 1.4GHz. This game loves CPU cycles though, overclock that 6700K and you should see an improvement. Also lower a setting called "local fog detail" or something to that effect, has zero image quality improvement but affects FPS dramatically.

Can someone explain to me what V-sync actually does. For example, I loaded up Battlefield 4 I get a solid 150-200 FPS on ultra with sync off. When I put it on it literally halfs my FPS I get, do I really need it on?

V-Sync makes the FPS match your monitor's refresh rate. If you have a 144Hz monitor, you will have a cap of 144 FPS. If it's adaptive, it can go anywhere between 1-144Hz to minimize tearing. If it's not adaptive V-Sync, then you will only be able to have even divisible frame rate of your monitor - 72, 36, etc

I have a 144hz monitor, when I turned it on my FPS dropped to 60. Should I be having it on or off when playing Battlefield 4?

If you have 144hz turn v sync off. And than say for battlefield 4 you can type in the console command to cap at 144hz. I forget the command off the top off the top of my head. (Maximumfps_144 some like that ). As for single or duel Gpus it comes down to what games you play. 980ti is more than enough for 1080p. I have 2 780s overclocked and games like Csgo , h1z1 I use one card and it performs better. Than games like over watch and bf4 I use both which helps. I'm on 1440p 144hz g sync

The difference isn't huge. You CAN notice. Battlefield can be maxxed with 2 980ti's at 1440p.
