Better correct that to:
If all you edit is SD (Standard Definition) you will get slow-to-medium SLOW... if you try and edit HD you will get VERY, VERY AGONIZING slow
All you need is a better CPU, more memory and better disks (plural).

I suggest you get a laptop with Nvidia graphics for Premiere. The graphics would have little effect on AE. However since AE performance is CPU and ram that would not be a good config for AE. A quad mobile would still have some limitation in AE but be far better than that config. I would suggest atleast the 4700MQ and 16GB of ram.
