Some Advice on picking the right Mac for Mainstage

Hello, I am in between picking from 2 different Mac's who's main function will be performance with Mainstage.

I have an option of a...
Refurbished MacBook 2.4GHz Intel Core 2 Duo - Aluminum
13.3-inch 1280-by-800 pixel LED-backlit display
2GB memory
250GB hard drive
8x SuperDrive (DVD±R DL/DVD±RW/CD-RW)

OR

The standard Macbook Pro 13-inch: 2.26GHz
2GB Memory
160GB hard drive1
NVIDIA GeForce 9400M graphics
SD card slot


Does anyone have a suggestion as to which would be the better Mac to get for Mainstage?

Thanks!
