Is Pose Mode only use CPU?

Hello,
My office PC is too old (intel e8300, R7 240) , Low FPS on Play animation, I want to upgrade.
No need Render, only Pose Mode/Edit Mode.

Is the performance of Pose Mode sensitive with GPU? can intel NUC i7-677OHQ be chosen?
Thanks!

Hi, if you use subdivide you can check Opensubdiv and switch on your GPU in User preferences > System.
It will help a lot for animation.
Sculpting is mostly CPU but it is possible to sculpt 1-2 million polys or it is something wrong.
DonĀ“t use subdivide for sculpting, use multires.
Every i7 is sky rocket compare to your e8300, R7 is not bad you can use it further.

Cheers, mib
