ok so if I overclock my monitor to 90hz and play crysis 3 but my cards are not powerful enough to display 90 fps will the game not look as good

Do you gain any benifit from having 2x GTX 780s instead of a single card on a 60Hz monitor?
Answer: Absolutely... what ever SLI supported game you have is going to get performance from two cards instead of one. (imagine two horses dragging a wagon instead of a single horse)

I, myself, upgraded to 2x EVGA GTX 780s and the performance almost doubled in all the games I play, that includes FarCry3, BF3, BF4, Arma 2, DayZ, Crysis 3 etc etc etc...

my advise to you is that your next upgrade should be a low ms monitor with a high refresh rate. my advise to get THIS monitor due to its specifications being the best gaming monitor in the market in my opinion.

I hope that gives you an idea biggrin.gif

Correct me if I'm wrong but Adaptive Vsync is the same a regular Vsync when your at a steady 60fps because the adaptive doesn't kick off until you go under your refresh rate, so if your at 60fps then the input lag is exactly the same as regular vsync

when benchmarking my fps using fraps with v-sync disabled is my cards working harder then if I was to have v-sync enabled because I am getting more fps with v-sync disabled

Here is what i recommend you to do.

1) play your game and check if you are able to play most of the time at 60 FPS... if you do... then you can overclock it to like 70-75Hz and check if you are able to play it at 70-75 FPS most of the time (overclocking from 60hz to 90hz is kinda extreme and not very practical i believe)

2) if you get to the point were the cards arent able to push more than for example... 70 FPS then there is no reason / no need to overclock your monitor more than 70 Hz

My personal opinion is you should stick with what monitor you have and then upgrade to a higher Hz monitor later if it is really bugging you biggrin.gif

It will look the same, it will just not render as fast.

Its really an experience thing. You wont understand the benefits of the higher refresh rate unless you try it.

I am not exactly sure of the details of regular / adaptive vsync... but personally... everytime i see the word "Vsync" I turn it off right away if the game is a FPS game.
but in OP's case... seems like he runs Vsync all the time so i am trying to provide him with the best solution / answer that resolves around his issue biggrin.gif

yes that is very true... when i had a 5ms 60 Hz monitor, i always thought it cant get any better and even if it did, it wont be that big of a difference... BUT THAT WASNT TRUE ! biggrin.gif until the day i pulled the trigger on high Hz monitor with low ms response time. the experience was really game changing.

Pushing a 60hz screen to 90 would have to be damn good luck, but yes that would make the cards work harder(because they want to draw 90 frames a second and not 60).

Grab GPU-Z(sensors -> log to file) or MSI Afterburner(detach the monitoring tab to see more) and you can see how hard the card is working. You can then switch from Vsync on or off to see the difference.

Xboxmember1978, You are right, Adaptive Vsync just dynamicly switches vsync on and off as needed. This avoids the drop to half frame rate on games that do not triple buffer[triple buffer just adds input lag anyway].

You can never have TOO many graphics cards or TOO much RAM.

If your MB supports it......than load it onboard.....

Also the higher refresh rate will make tearing almost un-noticable.

If you do OC the qnix make sure to also try a comparison with and without vsync.

I come from playing CS 1.6 on a sony CPD-520GS, Thats a CRT that does like 200hz at 800x600. I went from playing "somewhat" competatively.

When It died was when I purchased my first LCD, and this is before there were any above 60hz ( that I could find ). This was my first and only experience where tearing was bothersome.

Since then, it has been high refresh or bust, and I hope you experience the same level of smooth and tear free ( noticably ) gaming that I always aim to provide for myself.

the 780 SLI is a good match for 96-120hz overclock on the qnix. Enjoy the setup!
