You can get a lot of high-end notebooks. Sager make them, as do VoodooPC and Hypersonic. Of course they are pretty expensive, but they are very good (I'm getting a Sager 5720 dual core once it comes). There are a few 15.4" notebooks with numpads if you can find them, but nearly all 17" and 19" ones have them.

I think you should be able to play FFXI with this notebook you've shown us. But if you're willing to spend a bit extra, you can get better ones.
