I would really just do 2 things. First, look up a list of cards to see what desktop gpu it would compare to. Probably more like a 5550 for a desktop... then just go by that to see if it meets a game's system requirements - although when they give those they hardly ever seem to take monitor resolution into account. Your resolution is pretty small, being a laptop and all, so it's a bit easier for you system to run games.
On another note, Intel graphics are NOT for gaming at all. Intel graphics are simply meant for 2D stuff, and can only run games at the absolute minimum settings. You need a discrete laptop GPU for gaming, aka a "mobility" card.
However, there is hope! Early next year Intel should be releasing their Sandy Bridge CPUs, the next step up from the current i cores - they're still i cores, just with a die shrink which includes adding a GPU processor on the CPU. In some initial reports, it performs at least 3 or 4 times better than current Intel integrated graphics. We're talking at least as good as the OP's mobility card! Very impressive for on-die grahpics, however, in the desktop market this is a waste of space for enthusiasts. I think combining that with the fairly locked down core, the Sandy Bridge CPUs will be a hit only with laptops and very mainstream systems.
