I have a i7 7700k not clocked and 32gb of ram at 2134mgz and 1060 3gb. Do I need to upgrade to another card I'm max out on settings and the screen flutters when I pan to left and right. Also when ASN download new weather FSX  loads the scenery and textures with the window coming up In mid flight ... 

Not really especially if you clock that cpu up to 4.8 - 5.0.  A GPU with more ram will give you better results but with the 1060 you should be able to get acceptable performance. Delete your p3d config file and let P3D build a new one. Also delete the shaders at %appdata%/local/lockheed martin/prepar3d v4. Then slowly adjust your settings upward. Find the LOWEST FPS setting that will give you the smoothest performance. Remember, especially with P3D - high FPS does not equal smooth operation.
