Dolphin on a Laptop

[japan1]

I'm, sadly, having to go for a laptop for uni, so how does dolphin run on laptops?

In my price range, the most prominent GPU's seem to be Intel GL40's, X4500's and Nvidia 8400M's. All with modest C2D's around 1.8GHz to 2.4GHz and 4GB of PC6400.

So, any opinions on if a laptop like above would be ok for Dolphin?

I'm running a P4 2.8GHz HT, 2GB PC4200 and an 8600GT at the moment, and it just can't get more than 20 or so fps in Luigi's Mansion

I get 20-30 FPS on Fire Emblem: Radiant Dawn and about 35-40 FPS on Fire Emblem: Path of Radiance.

I have a Core 2 Duo 1.67GHz, 2GB RAM and a Nvidia 8400M GS. I don't know for other games, but my laptop's been fine for me (for now, getting a new one soon).
