My computer plays games very well. Why? Take a look at it for me,

The 5450 bit width is only 64 bits, the video memory is GDDR3, and your video memory capacity is only128 m. These parameters all determine the poor game performance of your graphics card. Generally speaking, the game needs a bit width of 128 or more, and the memory capacity is at least 256 mm. If you play online games, you can match 9800GT, 5 12M GDDR3 memory.
