Hey people. So I'm a sound designer, mac user, and an avid console gamer. But I just got my new G5 Dual-core 2.3GHz with the NVIDIA 7800 GT and Apple Cinema Display 20' Flat Panel, and I need some advice. I'm new to non-console gaming and high(er) end video cards, so I'd love any advice on what are the best video settings for Halo. And/or any video games advice in general for a newbie to the mac gaming scene. I'm just looking for the smoothest game-play possible with no screen distortion. Let me know. Thanks.
