Darren ~ I don’t think I’d go that far. FCP7 is still an extremely capable NLE. Slower in comparison to PP or MC – yes, but it’ll still get the job done.
Karim ~ You’re MacBook Pro should still get the job done. However, because your video card is ATI you won’t get the great benefits of the Mercury Playback Engine that harnesses the power of CUDA technology from Nvidia. CS6 should start to change this as Darren alludes to since they will begin integrating more Open CL code to harness the power of ATI cards (since that’s all that Macbook Pro’s ship with currently). Also impacting your playback will be where you store your media – is it on a network attached RAID, a firewire drive, a USB drive, an internal hard drive, etc. Also what type of media – SD, HD, ProRes, Uncompressed, etc. Further how many filters, FX, etc are you applying in the timeline.
Realtime playback is great and PP is making leaps and bounds in that area, but there are limits. There are always limits! If you have an older machine (i.e before 2010) that can impact things. The very nature of being on a laptop instead of a desktop is a limitation as laptops don’t have the same muscle as a desktop (memory, processing cores, GPU, etc.). I haven’t gotten my hands on CS6 yet, so I can’t speak to whether or not that would help your situation. However, running ATI video cards (as your Macbook Pro is) certainly impacts your ability for smooth realtime playback.
