And that's just my laptop, the P-7805u FX. The newer P-7915u FX has a slightly better CPU and slightly better graphics card, so those games will perform slightly better on it than on mine. I think it would be an excellent purchase, especially with it's very low price compared to other similar laptops.
Another possibility might be an Asus G71Gx variation.
Yup, the GTX 260M is a good step up from the 9800M GTS. And I agree that the Asus would be a good alternative, though a little more expensive.
