If you were going to order a new PC, and you had the option to choose Windows XP, XP 64 (Assuming system is 64bit), or Vista what OS would you choose?
The devil you know is often the devil I opt for. In this case I know Windows XP sp2. But since everything is gearing toward Vista, wouldn't it be prudent to go with vista?
Choices choices choices.
This is roughly the system I am thinking about buying with some minor tweaks.
