A follow-up on the issue I was having:

* Dropped hardware acceleration slider in Windows down 1 notch (Full --> Standard)
Adjusting these settings solved my problem for sure (I've had a fully stable system for almost 2 weeks). The hardware slider in Windows had NOTHING to do with the problem (I've since put it back to Full), nor did the PCI slot.
A co-worker of mine was discussing his AMD's "Cool&Quiet" feature, and we compared thermals (Opteron vs. Core2Duo). He was baffled by why my core temperature was around 50-51C, and the fact that FID was not fluxuating, thus increasing my overall system temperature. I pointed out the BIOS options I had disabled, which ultimately led to me re-enabling some of them to see what I could figure out.
For about 10 hours, I ran with these settings, and let RMClock run in the background.
* BIOS: Enabled: CPU Enhanced Halt (C1E)
* BIOS: Enabled: CPU Thermal Monitor 2 (TM2)
* BIOS: Disabled: CPU EIST Function
* BIOS: Disabled: Virtualization Technology
The result in RMClock was a FID that would fluxuate between 6x and 9x (thus changing the core clock between 1600MHz and 2400MHz). VID remained locked at 1.325V. Core temperature (when NOT in games) was around 46C, and when in games, around 51C. System temperature (now that I have my case closed) was around 37C, CPU temperature was around 34C.
About 10 minutes ago, my system hard-locked (no mouse response, etc...) -- but only while I was playing FFXI. (Goes back to my original post, where my system would only crash in WoW or FFXI or other intensive games).
I'm now trying these settings:
* BIOS: Enabled: CPU Enhanced Halt (C1E)
* BIOS: Disabled: CPU Thermal Monitor 2 (TM2)
* BIOS: Disabled: CPU EIST Function
* BIOS: Disabled: Virtualization Technology
Same thing as above (VID remains locked at 1.325V, but FID fluxuates). Temperatures are the same too.
We shall see. I'm left thinking the C1E feature is what's causing the pain...
Has anyone else played with these CPU features, and if so, have they had system instability?
