Virginia, if you really want to dive into 64bit then I would advise you to await the 64 bit Windows 7. Windows 7 is slated to be available around the end of 2009 or the beginning of 2010. As it is right now most laptops/desktops which are multi core do support a 64 bit OS, so a future upgrade is available. If you are looking for a motherboard for 64 bit try to get one that supports more than 4 gb of ram, 32 bit supports up to about 4 gb while 64 bit supports much more. Pay attention specifically to whether the cpu you choose can support 64 bit. Many software apps still are 32 bit but there is the odd one available that is 64 bit, there is a good list here for all 64 bit OS's http://www.start64.com/index.php?option=com_content&task=blogcategory&id=0&Itemid=55 or http://tinyurl.com/f6gs6 Peter Kaulback Virginia Da Costa wrote: > 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?
