Graphics card replacement on late-2007 MBP

[ftbtef]

Hi, I will soon be receiving my dad's old Macbook Pro (2.2GHz, 2GB ram) and I was wondering if it was possible to replace the Nvidia GEforce 8600m gt with another 8600m gt with higher vram (the current one has 128MB, but I can get one with 512MB). I am interested in playing Cider ports of certain pc games, and I have seen videos of GTA IV running on one of these cards. Thanks for any help.

EDIT: I also know that this computer meets GTA's minimum system requirements for everything except vram, where the req is 256mb instead of 128.

The GPU is soldered onto the logic board and thus cannot be upgraded.

The GPU is not user upgradeable. You'd be much better off buying a windows pc if you need to game.
