This will be dedicated to the machine. In fact the computer will be in the machine. I just want to be able to open and use BobCad if needed, not for it's main use. I will do my main CAD and CAM stuff on another computer.
The reason I ask about service pack 3 is because this computer does not work well unless I get all the updates. For some reason there is something it does not like about SP2, or rather it may be one of the updates you only get after loading SP3. Anyway, it works perfectly when all the updates are applied.
So, if SP3 is a problem, maybe I better put a bigger hard drive in and rin windows 7?
I already own XP for this machine though, I would have to buy Win 7.
