The usage of caspar depends first on your needs. When you stream a sports like football (soccer) - less changes of the result - , you can stay at your photoshop solution.
For sports with fast changes (Volleyball, Baskeball...) you could use caspar.
When using Caspar, I think you don't need photoshop while streamning. In this case, you can try, if caspar runs on this notebook. The software itself is freeware, so you'll only invest your time. If you want to create your own templates, I think you need flash, but I am not yet so far...
The first experiences of success you have on the first evening, after trying coding examples from the forum.
Here some tread to this theme. Maybe me experimets (without Caspar) are interesting for you...
Maybe take a look to the following threads.
