You could use Resource Monitor to see how many hard (page) faults you are getting. You will always get some no matter how much memory you have but if you are getting a lot, you need more memory. On Win 7, the quickest way to start the Resource Monitor is Start/Run and then type "resource monitor" (I don't have Win 10).
Remember that since you are using an SSD and the page file is on the SSD, any paging will impact the lifespan of the SSD.
I would add more memory and switch to 64-bit, but make sure that you can find 64-bit drivers for your hardware. I have 12GB and can run without a page file (although Windows Update will sometimes decide to create one for me).
