Suggestions for thinkpad x200s upgrade

The thinkpad x200s uses intel integrated graphics, and to play 3d games you need at least a mid-range discrete graphics card from ATI or NVIDIA, such as the ATI HD5650 or the NVIDIA GF 240M, which are mainstream gaming discrete graphics cards. Again, thinkpad is a business oriented book, not equipped with mid to high end gaming cards, even if it is a high end business T series is also using a low end consumer or professional graphics cards, and W series because of professional use of professional graphic cards, because of the different graphic processing algorithms, playing games is quite poor. Suitable for gaming is Lenovo's Ideapad Y series, which are consumer gaming laptops, such as the latest Y460A equipped with ATI's 5650 or 5740 gaming graphics card. So don't use thinkpad for gaming, let alone the X series for portability.
