How does my iMac's graphic card compare to the 9400M?

Hi there. I am looking to replace my iMac for a MacBookPro plus an external display. I am looking for portability but also for power as I do some photo work in PS with RAW files and have a quite large iTunes library (about 150gb). I would love to have the high end 13" MacBookPro rather than the 15" because of the size and weight.

These are my actual iMac's specs:

2.0Ghz Core 2 Duo
2GB RAM
ATI Radeon HD 2400 128MB

So the question is: Would a 13" high end MacBookPro suit my needs? Is the graphic card's shared memory an issue here?

Thanks everybody!

If memory serves me correctly, your year old iMac has a slightly better video card then the new low end Macbook Pro's with the 9400m.

If you are doing PS work and use iTunes, that's all 2D and CPU processing power, which doesn't rely on your video card for squat, so while your video card wouldn't be as good, you probably wouldn't ever notice unless you get into 3d rendering or video games.

Thanks jaded. I don't do any gaming or 3d rendering.
