What is equivalent to a Mobile Intel(R) 4 Series Express Chipset Family video card?

I want to play some old games in my laptop, and its onboard video card is a Mobile Intel(R) 4 Series Express Chipset Family, as most of game requirements charts uses comparatives as Nvidia or ATI, I wanna know to which nvidia or ATI card my laptop on board card is equivalent to.|||See the source - benchmark info of most of the available graphic cards. As you will probably notice, Intel card sucks, you won't be able to play comfortably on it.
