9400m or GT120 running second display

[stars_fan]

Anyone have their 24" iMac hooked up to a second 24" running 1920x1200?

Which graphic card do you have?

I'm going to the store tomorrow but I'm guessing they won't know much.

I'm looking for confirmation that I can have say a movie running on one screen and working (mail/safari/photoshop) on the other screen without things slowing down too much.

I have the base 24"

$1499 model with the 9400M and have a 24" LED Cinema display connected to it.

No performance problems so far, and I use the setup mainly for graphic design and web development.

Thanks I decided to go ahead and get the GT120 model.

I'm setup for web/iphone/osx development.
