I'm getting about 70 fps in Witcher 3 which isn't too bad actually. Game play is smooth. I was able to set up the display for g-sync compatibility in nVidia control panel @144hz and it seemed to accept it just fine. No tearing or stuttering in any games. I also set the games I play in nvidia control panel to "fast" for vsync and in the games themselves to "vsync off" if the option is there.

My Alienware Aurora R8 has a desktop app that allows you to set overclocking to either 01 or 02 and temp to either balanced or performance and power to either balanced or high performance. Unfortunately, it is somewhat dumbed down only allowing a max overclock of 4.3ghz. Also, the memory seems to be have really slow timings. I mean REALLY SLOW. I'll have to check if the Alienware case is large enough to accept a 2080ti and if the power supply is big enough to support it. Maybe a memory upgrade, an upgrade to a 2080ti and power supply to support it will kick this unit into a whole new class. This would be cheaper than a whole new computer but concerns of temperature would still remain since the Alienware case is small and might create an oven effect.
