I suspect that's really hard to say for anyone because, as with anything in life, the next question is... good for what?
For what I've read is a dual core at 1,8 GHz. I would say it is OK but not great. If you only use Office (or OpenOffice or similar) and visit Facebook and all that is more than enough.
If you're a serious programmer using compiled languages or a heavy gamer or an Photoshop professional, you do want more from a processor and this is Ok, you can work with it but you'll buy something better if you can afford it
