The system requirements for the Ms Office 2010 , that a hardware upgrade should not be necessary when you upgrade to Office 2010 from Microsoft Office 2003 or the 2007 Microsoft Office system. You might need to upgrade a supporting operating system. If you upgrade to Office 2010 from Microsoft Office 2000 or Microsoft Office XP, you must ensure that the hardware and operating system meet the minimum system requirements for the Office 2010 suites.
But as general rules, CPU and RAM requirements for Office 2010 are the same as for Office 2007, so if your computer meets the Office 2007 system requirements, you can run Office 2010. A graphics chipset will help boost the performance of certain features and disk footprint has increased (more on these points later), evaluate the computer prior to deployment to ensure it meets the minimum operating system requirements.
Minimum System Requirements:
- Intel Pentium III processor, 500 MHz
- 256 MB PC100 SDRAM
- Windows XP Professional with Service Pack 3
- If your current computer can run Office 2007, it can run Office 2010.
- If you’re purchasing a new laptop or netbook, it can run Office 2010.
- If you have a computer with a multi-core processor, it can run Office 2010 even faster.
- If your computer is currently running Office 2003, it’s possible that it can run Office 2010 (check the requirements to be sure).
BTW Microsoft plans also will release Office 2010 in web version (online version) , and even more interesting is FREE, woow..we'll wait!
