Here is the updated list. I want to order everything this evening after reviewing the list today. I've used several of those online PSU calculators and I'm thinking my current PSU will be okay for this upgrade and maybe even for one more GPU change. It's strong for a 560W but I'll probably end up changing it in a year or two. Here's a link to my PSU:
