I have all updated drivers for my graphics card, but i cant see, to make over 130 fps on a game like League of Legends. I barely hold 98 on Rainbow 6 Siege. I also tried rolling back the drivers and that doesn't seem to help either. Any idea ?

Heres a GTA V Benchmark

when you updated your drivers, did you do a clean ddu uninstall through safe mode and reinstall a clean current driver installation? sometimes old&new drivers conflict, yielding poor performance and instability. also sli is not really advantageous unless it's supported in certain titles. sometimes sli can even hinder performance. my two cents (after thorough research on the benefits and drawbacks of sli and crossfire from numerous video / article reviews).

Thank you for the reply, I did use DDU to uninstall and had a clean installation for the current drivers. Still about the same on my benchmarks. I do understand that SLI isnt suppoed to give your a massive graphical boost and may even lower performance than just one card.

Would SLI really bring my performance similar to a 960 or could it be possible something else could be going wrong?
