Windows 7 - Mobile Intel(R) 45 Express Chipset Family

Hi, I have lenovo g450 model: 20022
Under dxdiag> Display tab

It says Mobile Intel(R) 45 Express Chipset Family under name
and Mobile Intel(R) 4 Series Express Chipset
DAC Type: Internal
Approx. Memory: 780 mb
Current Display Mode: 1366 x 768 (32bit)(60Hz)

*** can someone interpret this information?
I need to know if the video card is good for gaming, capabilities or what I games I can play with it and what are not, if it can be upgraded, how much memory I have for Video card and is it also the same as Intel GMA 4500MHD?

Intel integrated cards on laptops are definitively not meant for gaming as they have lower clock rates and a small amount of video memory, you won't be able to run most games at a good resolution and most of them will lag a lot

The 4500MHD is a part of the 4/45 series families. I'd say 95% chance you do have the 4500MHD.

To give an idea of what it is capable of (or more like incapable of) look here,
