I have a Toshiba satellite A300 29N Laptop, core2duo T6500 2.1GHz, 4GB DDR2 RAM, ATI mobility radeon 3650 HD.
I"m a gamer and I would like to know if its ok to play games with my current configuration.
I play games like sims3, split second, undercover etc
Yeah, you could play a few games. I don't know what the requirements are for those games but it would really depend on the game itself. My suggestion is to look up the game's reccomended and minimum system requirements.
I believe that you CPU and RAM should be fine for gaming but your limitation would be your graphics card. I suggest you take a look at notebookcheck.net and see that kind of score you graphics card gets and compair that to the minimum and recommended system settings for the game.
