Well I was looking at dual core 939 chips the other day and got tempted.

But I don't know if my mobo will support one.

According to CPU-Z, it's as below...
Code:
Mainboard and chipset	 
Motherboard manufacturer	MSI
Motherboard model	AMETHYST-M, 1.0
BIOS vendor	Phoenix Technologies, LTD
BIOS revision	3.20
BIOS release date	07/08/2005
Would it run a duallie and would I need to flash the Bios?
