Not really, if one considers thr gaming benchmarks on notebookcheck,820m still has some juice(because nvidia likes to overclock its cards) whereas 8570m is just plain bad.
Just look at 3D Mark 11 performance which measures DirectX 11 gaming performance.

They differ by 1 point.
The poor benchmarks of games is because it was always tested with a very weak "U" CPU which could happen with the 820m also if the OP decides to buy the Dell Vostro.
