A lot of professionals take MBPs to shoots and use them as mobile workstations. Of course they also have Mac Pro setups in the office but yeah, MBPs work without a hitch. Just get a good FW or eSATA external HDD as your scratch disk and you'll be fine.
So yeah, the MBP is plenty strong. Figure out if you want portability or sheer power. If portability is any of your concerns, the MBP strikes a pretty nice balance between the two.
