Well this game may not be of your interest, but I think you should get your hand on Unreal Tournament 2004. I got this game from a buddy of mine for free a while ago. I got instantly hooked on it, and it pretty much runs on my laptop flawlessly. Sadly the copy I got was a hacked version. Seriously though if you're a huge fan of FPS games I really recommend this game.
Here are the system requirements in case if your wondering:
-Operating System: Windows 98/Me/2000/XP/Linux
-Processor: Pentium III 1.0 GHz or AMD Athlon 1.0 GHz or faster (1.2 GHz or faster recommended)-Memory: 128 MB RAM minimum (256 MB recommended)
-Hard Disk Space: 5.5 GB free
-CD-ROM Drive: 8X Speed (DVD-ROM drive required for DVD Special Edition)
-Video: 32 MB Windows 98/Me/2000/XP-compatible videocard (64 MB NVIDIA GeForce 2 or ATI Radeon Hardware T&L card recommended)*
-Sound: Windows 98/Me/2000/XP-compatible sound card (NVIDIA nForce or other motherboards/sound cards containing the Dolby Digital Interactive Content Encoder required for Dolby Digital audio.Sound Blaster Audigy 2 ZS card recommended.)*
-DirectX: DirectX version 9.0b (included) or higher
-Modem: 33.6 Kbps modem for LAN/Internet play (Broadband Internet connection recommended)
* Indicates device should be compatible with DirectX version 9.0b or higher.
According to your laptop specs you should meet those requirements with no problem, but if you have any questions regarding the game and/or the requirements, I'll be glad to help you with that.
