ATI 3470 good enough for Photoshop CS4?

Hi there,

I'm about to buy a new laptop and I have several doubts about which one to choose, specially when we talk about graphic cards.

The use I'm gonna do of the laptop is basically is photo processing with Photoshop CS4, watching films and downloading files. I won't use it for gaming or hardly.

I saw a Sony Vaio VGN-FW31 E with an ATI Mobility Radeon HD 3470. The laptop looks great but I wonder if the graphic card is powerful enough to manage the use I´m gonna make of it.

Could anyone here answer me, please?

Thank you very much indeed,
