Re: vist and quad core.....
All the Vista editions support only one or two physical processors, however, none are limited to the number of processor cores they will support. So yes, Vista will be able to handle quad core easily.
Intel Core 2 Duo is best at this point.
On a side note, AMDís new socket AM3 CPUs such as the "Deerhound", will be backwards compatible with existing socket AM2 motherboards so the upgrade path will be much smoother than originally anticipated.
Intelís quad core is suppose to operate at around 2.67GHz
