None of the above, my connex is 33down 5.5up, more than the 600kb up they recommend for streaming. It's also not the CPU, overclocked i7 is about as good as you can do right now, and people are getting good results rocking p4s.

Also interesting, many people have reported similar problems, while some have perfect performance. Once I run a streamer program, I can close everything including the program... leaving only 1 wow running on my machine + OS processes... and it STILL has the shit fps. The wierd thing is, the FPS are normal unless I attempt to pan, where as I said it chops out. Reboot the system and BAM I'm frapsing 40 man Battlegrounds and playing at 60fps full settings.

It's not my system, xfire/whatever else programs are changing some setting or causing some problem that fucks rendering and persists after the program has been closed.

Forum searches have yielded no solutions, only similar complaints. Maybe its win7 ultimate? Vista didnt do this... but that was an entirely different box as well.
