Introduction If you've had questions about upgrades before, you've probably come across this chart: If you already understand about upgrades, that's a handy reference! But if you are relatively new or just not totally up on the subject, it might introduce more questions than it answers. What are all these paths? Which ones are good, and for what? What should you upgrade, and how do you do it, and where? For the answers to these questions and more, read on. I'll be breaking this guide into multiple posts, so please be patient as I will be adding them subject by subject. I'll also leave a post at the end to compile a FAQ out of questions people ask in the thread, unless nobody does in which case I'll just delete it.
