O.K. Help a girl out.

I am filing my taxes. With our return my DH wants new tires for his truck. And we just had a $450 repair bill for his truck I had to charge so I have to pay that off. So, to be fair, he is letting me get whatever I want with the same amount of cash. I have been through 3 laptops in the past 5 years. This one is pretty good. But I can't do my homework sitting in my recliner. So I need to motivate myself to sit at the desk. I have been thinking that I want a desktop. So here is where I need your help. If they come with the monitor, it is usually 19" Is that big enough? I use my computer for music, homework and scrapping. So what size is your monitor?
Also, I really want to upgrade from PSE4. I could get PSE7 or I could go for gold and get CS4
So to recap...
Monitor size???
PSE7 or CS4??
Worth the money??
