Two things are going to be important while running Adobe Dream Suite CS4....RAM and processor. It really depends on your budget, if you want to spend the money you can get Quad Core processors in notebooks these days. The more money you spend, the more powerful notebook you get of course. What is your budget for a new notebook? That will help us guide you in the right direction
- For your processor, I would recommend an Intel T or P 9 series processors, they are great for notebooks

One of these will be just fine.
Intel T9550 / 6MB L2 Cache, 2.66GHz, 1066MHz FSB
Intel P9600 / 6MB L2 Cache, 2.66GHz, 1066MHz FSB
Intel T9800/ 6MB L2 Cache, 2.93GHz, 1066MHz FSB
- For your RAM, you will need 4GB running at 667MHz or 800MHz if you can find it. Adobe design programs are RAM intensive and will require that much RAM to run at full potential.
I really like Sager notebooks...I have had one for 2 years and never had an issue with it. Great notebooks from a great company.
