You mean GTX 1070? Well, to be honest, if you only use AE right now - not a ton, but it's changing. Also depends which version of AE you're on. There are now a fairly good amount of effects in CC2018 that are GPU-accelerated, such as transforms and motion blur, but fewer and fewer if you're on older versions. However if you use Premiere you should see a fairly significant boost to any function that uses Mercury playback engine, such as...video playback. Which is great! If you use any 3D apps or GPU based renderers like Octane or Redshift, you'll notice an even more significant difference.
