980 ti SLI 1920x1080 144hz

[Tungviktare]

Hi!

 

I have a question that i can't seem to find a clear answer to, maybe I can get some help!

 

 

My current setup is gaming at 1920x1080 at 144 hz - with a singel 980 TI card.

 

I have a simple question, if I decide to get another 980 ti card and run SLI with these, will it improve my gaming proformance? 

 

- Do not regard if its woth it money wise or anything like that.

 

 

I know its different game to game, but overall?

 

Thanks in advance! much appreciated!

Yes and no, some games could simply run worse due to lack of support, etc.

Performance wise -Yes if the game supports and drivers aren't crappy

Is it worth it?- Not at that resolution

Yes, i have two 980 ti's and it will improve performance, remember you'll need an sli bridge, and that you wont get double the frame rate

 

hope this helps

no not really

980Ti was meant for entry level 4k

aka 4ish times 1080p, If ANY games are lacking behind it cant be by much. 

You'll  be fine with a single 980Ti another is really a waste unless you want to do 4k 60fps

Thanks for the answers so far!

 

 

Nobody running the 1920x1080 144 hz monitor setup? with 980 ti SLI?

There is no point to. 980Ti is not needed unless you do 1440p 144hz or 4k

what CPU do you have?

 

If your GPU usage is >99% then another 980ti will help. if its not then it wont do anything at all.

Thanks for your reply!

 

I use i7-4770K

ok great - well as before, simply check your GPU usage using MSI Afterburner in a few games... if your GPU is at 99-100% usage and NONE of your 8 CPU cores are above 80-100% CPU usage then another 980ti will add some frames in games that support SLI.

 

The flip side of the coin is that your GPU usage might not be 100% but you will see at least one of your CPU cores at 100% - this means adding another graphics card wont give you a higher frame rate - it might up the average, and improve the minimum but the maximum will not increase...

 

The other other side of the coin is that both CPU and GPU are at less than 100% usage - this is usually caused by one of a few reasons:

• the game engine is shit
• you have v-sync on (and are hitting the vsync rate without using all your power)
• the game might be I/O bound (slow HDD)
• the game is forced to use HDD/SSD when it wants to use RAM (you don't have enough RAM)

Note: with increased frames from another GPU comes increased CPU load along with it. this will vary engine to engine as some engines will calculate physics and AI on a set tick (say 50 times a second) where as  some will calulate them every frame...

 

regardless of physics/AI - seeing as your CPU tells the GPU to draw vertices - the more frames the more draw calls the more CPU load.

Not all game utilize SLI, or one that do might not do it well. It reallllly depends on the games you are playing. For 1080p I would say stick with one 980ti. If you're venturing into 1440p or 4k consider SLI. In games that support SLI well it will obviously benefit you, but as others here are saying it's really not worth it. If you have that much cash laying around for dual 980ti's may as well start looking into 4k/1440p.

Thank you so much for these  hits, a got a much better perspective on it now!

1080p and 980ti SLI would be a ridiculous waste of money.
