Unless your friend specifically bought a laptop that provides upgradeable video, such as some models from Alienware and VoodooPc, whatever video chipset came with the laptop is what she'll have to live with.  these are normally embedded on the motherboard, and aren't user-upgradeable.  \n\nthat said, if this is a fairly recent laptop (made within the last three years) and has at least an ATI Mobility Radeon or Nvidia GeForce2go with 16MB or 32MB of dedicated RAM, or it's a very recent laptop (made within the last year) with a good chipset using shared memory (Intel Extreme Grahpics 2), your friend should still be able to install some playable games on the laptop.  games for teens and adults (Doom 3, Quake 4, Civilization 4, Battlefield 2) probably won't be playable,but less strenuous and older games (Civ 3, Unreal tournament) and younger kids games should still work fine.
