Is ATI Mobility Radeon 5470 1GB good

The AMD Mobility Radeon 5470 is a good chip, but only twice as powerful as an integrated 4250 on an AMD motherboard, 80 shaders vs. 40 shaders. So it is the absolute low-end when it comes to serious gaming on a laptop, only good enough for DX9 games or WOW. For HD/BLU-RAY video anything from an HD3200 up will do, but for gaming on a laptop, spend the extra US$150 and get an 1GB HD5730 or better in your laptop, ok?
