I currently have a 32bit version of Windows XP Professional on which I have installed the following 32bit software:
- Chromium 13
- Adobe Photoshop 7
- Office 2003 Professional
- Altiris 6
- Microsoft SQL Server 2005 Management Studio
- Microsoft Visual Studio 2008 Professional
- VirtualBox 4
- Sophos AntiVirus 9
I have 3Gb of RAM and apparently the computer has a 64bit processor. This is not enough RAM for my day to day usage needs. I personally believe I need 6Gb+, probably around 8Gb, so I can have many virtual machines open, plus photoshop and or visual studio. At the moment, if I open 1 virtual machine, 1 complex photoshop file, the 3Gb is all used up.
So my question is, if I install Windows XP Pro 64bit, I know my computer can theoretically handle 8Gb of RAM even though a max of 4Gb is recommended by the manufacturers because of the included 32Bit os, will I have any problems reinstalling all the old 32Bit software listed above onto the 64bit os? Or will I have to get 64bit versions of all the software?
