Office X was designed for OS X (hence the name), so it'll run under Rosetta on an intel Mac. So it will work, but TBH it will still be fairly slow and in order to be compatible with newer versions of Office, you might want to look into the latest version.
Office 2008 is fairly affordable for home / personal use!
