The only issue I've had specific to running AMD x86_64 is that  
LCDproc doesn't compile for me. INSTALL states, "The server needs to  
talk to the LCD display. At this time, it works on very little more  
than on the Intel i386 (PC Compatible) architecture."

I can't comment on speed except to say I'm happy with it. Before  
this, I was running a dual PIII-733 box and wasn't happy with the  
speed for things like transcoding and I never attempted HD with it.
