Should I upgrade (Photoshop Elements)?

[momtutu]

I currently have Adobe Photoshop Elements 3. I'm doing fine with it and my new fun hobby here!! But as I'm looking through tutorials, it looks like the ones for PSE3 are becoming somewhat farther and fewer between vs PSE6. Should I take the plunge and upgrade? I know one thing 6 has over 3 and that's the ability to make text boxes - that would be sooo helpful!!

Any ideas?
