Graphic Booster

If you really want to game properly, you will need to get a laptop that has a proper GPU.
Intel's IGP's can not handle gaming.
And no, there is no way to upgrade your laptop for gaming...

It is posible to upgrade a laptop's graphics card, however, it is very expensive, upwards of $600.

Yes, but only if the laptop is a high end gaming one and designed to take the upgrade.
A low end Acer does not stand a chance of accepting a GPU upgrade.
