Thanks everyone for your help, I really appreciate it. 

I've uploaded an album on imgur with the requested screenshots. Here's the full album: http://imgur.com/a/RSwjr

My Dolphin Graphics Configuration:


My overall Dolphin Configuration:



Dolphin running at 2x native (720p) with the Task Manager open:

As for overclocking- I'm not entirely opposed to it, but to make a long story short, I've been given a gift to upgrade some computer parts. I figure I might as well take advantage and I might as well get something that may help Dolphin work better. But if I don't need to upgrade my CPU, then I could spend more of the gift money on an even better GPU, for newer PC games. 

Edit: Woah, original pictures were super huge.... tried to make em smaller... They're still pretty big. <_<
