I'd say watch out for NS2, it crashes on a lot of nvidia hardware when you try to shoot anything, and the devs have been "working on it" for two months now with no results
We play it at work for after hours LAN partys and for the most part its been working fine on our NVIDIA hardware. It did crash on me once though and I was not able to join the game again as it said I was still in it.
Seems like a great bundle... but I already have those games installed. The only complaint with NS2 I have is that I get 20 FPS less in Linux (in Windows > 40 and Linux < 30 fps, with same settings). I've got a GTS 450 and for me it is unplayable on Linux :/. I really hope performance of this game on Linux, will improve.
