I just checked and I have the 1070! When I bought the computer, the difference between what a 1070 vs a 1080 did for P3D v3 were insignificant. Now with P3D v4 and XP11 that lack of difference may no longer be true in all cases. So far I have had no FPS issues with P3d v4 or any addons for it. That being said, as far as XP11 goes, prior to this software, I ran XP11 with full sliders to the right and had no issues of framerate problems at all. Might be getting close to time to upgrade the video card!
