With AMD's recent big price cuts and dual processors being all the rage, I'm thinking of getting one.

My motherboard (a misnomer if I ever saw one) - ASUS A8V Deluxe - apparently supports the AMD X2s, needing a BIOS upgrade to do so.

I've replaced just about everything in a PC box over the years, but never a processor with a heat sink.

Is there a specific sequence of events that have to be done?
- I *guess* I can update the BIOS before even buying the CPU. Correct?

Can I do it in-situ, or do I have to dis-assemble the box to do it?

Is there some trick to be aware of to pull the old one?

Any hints/cautions/etc are welcomed.
Thanks
