I heard you loud and clear. If it ain't broke, don't fix it! YOGI perfectly explained how to make your XP computer fit in case you do run into problems with updating the Canon software; for RAW you will need to do that because the older software doesn't know how to handle the T4i RAW files. If I were you I would start using your current computer until the hardware proves to be too slow or XP is indeed too old for newer software.

In case you need it: there is a hardware compatibility check program available from Microsoft that allows you to check if your computer can be updated to Windows 7 ( http://www.microsoft.com/en-us/download/details.aspx?id=20 ). Helps to prevent a frustrating rollback.You have sufficient memory for sure. It will probably complain about your video card not supporting the transparent Aero desktop, meaning you will get a non-transparent desktop like in XP.
