64MB DDR ATi M7 Mobility Radeon 7500

Anything you guys out there can give me on this "64MB DDR ATi M7 Mobility Radeon 7500"?

I just bought myself a new Dell;

Inspiron 5100, Intel® Pentium® 4 prosessor - 2,4GHz, 14.1" TFT XGA (1024x768), 256MB DDR RAM/266MHz (1x256MB), 64MB DDR ATi M7 Mobility Radeon 7500.

How would this work for me in Half-Life for exampel? With FPS?
