Ive recently purchased an additional GTX 770 by EVGA to go with my computer. Im using a i5 4670k processor. Ive noticed in most games that i play the performance is the same or worse than when i use the single 770 on its own. ive enabled SLI in the nvidia control panel but i don't know what else to do.

750w is kinda low and it's a mediocre unit. I know I wouldn't run my setup with it.
LOL- last I heard this game has issues with SLI so your best just using a single card
GTA V- you will be Vram bottlenecked where you only have 2Gb of usable vram.
Ark SE- Its still in early access which means its not optimized and may not sully support SLI and still has always to go, as development goes on hopefully it starts to run better.
Try running the heaven benchmark on the extreme preset and see what it scores with SLI and without.

you know it only works in full screen mode and not all games fully support it without tweaking?

games you are playing + full specs, especially make and model of power supply?

I wasnt aware of that though i do play most of my games in fullscreen mode. My psu is the Corsair RM750.
Games i play:

  • League of legends - full (120fps (i used to get around 200+ with 1 card))
    GTA V - meium / high (50fps)
    ARK SE - medium/ low (15 fps)


I have 2 EVGA 2gb GTX 770 SC's

The games i play are on the same settings as before.

ive run the benchmark and on a single card it averages 46 but with SLI it averages around 86, so its working then i guess, maybe i should try playing better optimised games instead :3 thanks for the help
