Worth upgrading a 2005 Mac Pro G5 dual core (2.3 GHz)?

[JDM0725]

I got an old abandoned G5 mac pro from 2005. I've never owned a mac or upgraded one. Im primarily using a windows pc for daily use and even gaming. Seeing how this mac is from 2005, is it worth upgrading CPU, GPU, RAM, HDD or would I be better off making a hackintosh out of it?

I have specs link listed below:

There's no effective way you can upgrade the CPU or GPU these days, unfortunately. You'd probably be better off using it as a case for a hackintosh, as the G5s ran very hot and are limited to OS X 10.5 at this point, which is about a decade old.
