I am looking at buying a Athlon 64 laptop, and i was wondering if i need a different version of XP, I have heared of XP-64 would i need this. The supplier i am looking at offers Xp with it but inwas going without it to save some money (being a student) but will this come back and get me later?
There are very few applications that take advantage of the 64 bit architecture. Windows XP - 64, hasn't yet been released, however, the system is backward compatible with all the normal 32 bit architectures.
The only 64-bit operating system that you can sensibly run at the moment is Linux. Unless you already have some expertise in Linux, I wouldn't recommend it.
Win XP 64-bit will run on your laptop when it is released but will bring you no advantage anyway. Before you can reap the benefit, the software developers will have to release 64-bit versions. 32-bit versions will run, but probably more slowly than on 32-bit WinXP.
The real advantages of 64-bit come in addressing more memory - this will really only be valuable for operators of huge databases.
32-bit XP will run perfectly well on your laptop and will be supported for the foreseeable future - certainly the lifetime of that laptop.
