Some good PC games for my laptop?

I just got a laptop, and i'm trying to figure out what games i should get. my system specs are; 2 AMD Turion Dual Core RM 70, @ Ghz perfomance running at 3.00 computer speed, 2.7 GB RAM, Vista operating system, NVIDIA GeForce 8200m video card, DirectX 10, 76.7 Gb free space.

Any games will do for me. I like RTS, FPS, and rpgs. (I have been meaning to get the orange box)

Go through the classics and work your way up til your computer can't run them!

Games like Deus Ex, System Shock, Mafia, all the Command and Conquers, Diablo, Neverwinter Nights, the list goes on! I always find just looking through the top rated reviews works, you are bound to found the best stuff.
