Your processor is up to the task, but cram as much memory as possible into it and don't expect it to do much more than the basics. My mom has a strawberry iMac (333mhz, 288MB) that is running Jaguar. It's a good email/web/word processing machine. The OS is a little sluggish but it's acceptable. Panther is supposed to be a little snappier--we'll see.
