GTA IV System Requirements Exception

[LiNuX]

I would, but it's in a laptop...so to my knowledge isn't RAM the only upgradeable part of a laptop?

You can upgrade any part of the laptop if you know how to. They're just more expensive and the parts usually have to be customized for the case which could be harder to find in the case of a graphics card, especially an intel integrated one because there may not be room on the motherboard or case for an addon card.

So the only thing you could do right now is get the game and give it a go on low settings. I know it'll run but I doubt it'll run smoothly for you.
