|There are gaming laptops out there but their not under $400. But for those games you mentioned you could easily get a Basic laptop with an HD graphics card that will run anything old and some new games at low frame rates. |
What your looking for is a cheap HD graphics card like:
Intel Graphics Media Accelerator HD
ATI Radeon HD 4200
They are not the greatest at gaming but will do old games nicely since HD graphics need alot of shared memory. Some of those cards can go as high as 2gigs of shared memory.
