Which PC components to upgrade?

Hi yall,

I have a computer with the following components:

​

Mainboard: MSI H110M Pro-VD

CPU: Intel Core i5 6500 @ 3,2GHz

RAM: 8 GB (thinking about upgrading to 32 GB)

Graphics: GTX1060 3 GB

Storage: 1TB HDD

​

Which of these components could I upgrade in order to get better performance? I do use a lot of Mods and play with at least 1920x1080p resolution but prefer to use a higher res.
