I somehow find it reassuring that a product that was put out years ago is "safer" than a product that was still available months ago by MS.
Wonder what version of Jag they were using?
From what I have read this is normal when your machine has a KP - the fans freak out. You might want to have look at your logs to see if you can find the cause of the panic.
Laptop or Desktop?
Laptop, definitely as it is woefully expensive to fix.
You have a year before you have to make your decision so see how your machine is panning out.
