Halo 3 is going to come out for pc around the same time as DX11, when every game will look like crysis, and Halo will still look like Halo and nobody will play it.
Anyways get the gaming rig, while I suspect Halo 3 and Crysis will score about the same, you have to take into consideration the hype of Halo 3 and knock a few points off. Although I'm a bit worried about the Crysis multiplayer. Far Cry's multiplayer was abysmal, I'm not talking about the gameplay, but I couldn't even connect to it. EA is a bit better about that then Ubisoft but I expect there will probably be around 1GB of patches before it gets working properly, and this might hinder Crysis.
Also Halo 3 is on a console, so while it will be insanely fun for a while, after a few months you will grow bored of it. The only thing new will be maps. While Crysis is on PC and there will probably be lots of mods and other goodies.
