I been thinking of getting a new laptop but would like to get one that is good for gaming.   The system I have right now is an Aspire Series 5610z and Yes it a good system.

The current system of this is:

Intel Grahics Media Accelerator 950

120GB HDD
DVD Duper Multilayer burner

[ad#ad2-right]Now I want to consider getting another laptop but don’t know which would be good for gaming.  I know it will have Vista.  I actually like the O/S.  Although people don’t.   Here is what I want from my readers.  I want to know which system you suggest for gaming, and need as much detail as possilbe I would like to buy this from Amazon but if Amazon, so please give me links to the amazon page.   I am wanting to play some current games on this from last year but this system is not able to do some of the games.  So leave a comment and tell me which ones you suggest.
