I am both new to these forums and Mac computers. I have finally decided to buy a MacBook Pro. However, I am not sure which processor to choose, the 2.2Ghz or the 2.4Ghz. I tend to have lots of applications open at once, I would use spaces often, and would like smooth coverflow, and aqua effects. Will I notice a significant difference between the 2.2Ghz and the 2.4Ghz processor options? Will I notice a significant difference between the 128mb and 256mb graphics cards if I don't play games? Cheers, J.K.
