I am moving over from mac, (will have powerbook for it if I need it).

I am going to use live 5 for sequencing and pro tools LE for mix down. I plan on buying two UAD cards for use. Dont want to spend the $$ that ten spent on his rig, but dont want to have to upgrade for a couple years either. With all that is out right now, and never owning a PC, I am a bit confused to say the least. I am pretty sure I want to head the AMD route, but dont know if dual would be better or not. Live only is capable of using 1 processor, but in pro tools I might need all I can get. Or if I want to fire up another sequencer, the extra processor might be handy. So, I am open to any suggestions you guys have. Dont need a monitor.
Thanks in advance
