@Saithes: Sweet. Thanks! I'll have more to toy around with after Friday now unless my friend knows how to effectively do this. =) I've got to step out for a while, but I'll still be sure to keep you guys posted after we try some new things out, and I'm also anxious to see if anything has helped out fps in raid tonight. I'll keep you guys posted on that as well.
Thanks for all the help so far today, everyone! =)

I'm now leaning toward the motherboard being the biggest issue. I have a guildie with the exact same processor, a much lesser video card, and yet he has a board supporting the AM3.
This is his board: ASUS M4A78T-E Motherboard
He gets 50 fps during raid combat in 25 mans, according to him. I've never even touched that, and I seldom even get those numbers while standing still in Firelands.
