I just upgraded my computer to Vista 32 bit and read in the instructions I can get a 64 Bit DVD for a nominal fee by contacting Microsoft. I have a Pentium D 915 CPU and D945GPM board and from what I have read will handle the 64 Bit. I like to keep my system up to date and I do alittle gaming. I thought I would ask here in the forums if I should go ahead and update to the 64 bit while I can get it for a cheap price? All responses would be appreciated.
