Generally hardware is not 32-bit nor 64-bit, it's driver level. So you have to find out which hardware (motherboard, video card, and whatever else) has 64-bit (XP or Vista) drivers. Software HAS to have 64-bit support, so you'll probably have to get 64-bit versions of all your software and programs. Some may already have 64 support, but not likely. In typical computing, you don't need a 64-bit OS......and you don't want Vista. You can get XP in 64-bit. Support for XP is out to 2014. But you don't really need "support" for it anyway, it's not like it's going to stop working. -Clint God Bless Clint Hamilton, Owner http://www.OrpheusComputing.com http://www.ComputersCustomBuilt.com ----- Original Message ----- From: "Virginia Da Costa" I am planning to buy a new custom-built computer, being fed up with the slowness of my ancient laptop and using other people's cast-off desktops. Question is, whether to change to 64 bit hardware and Vista 64 bit? Windows Secrets article dated 25/09/08 said "Don't go from XP to Vista unless you go 64 bit" I have been very satisfied with XP in general and don't really want to change, but it seems a pity to buy a new machine and use an OS which is soon going to run out of support (although extended support is due to continue for a while). On the other hand, should I wait for Windows 7 - but that might mean waiting a long time and I need a new computer quickly! What are the implications of moving to 64 bit? What about existing drivers and software? Will all that have to change? What kind of motherboard supports 64 bit? I know there are definitely fewer memory limitations, but what about all the everyday apps and such things. I look forward to your expert feedback before making a decision.
