600 EUR is 405 pounds.
Anyway, in general I don't like console gaming all that much (with exeption of some titles (mainly Nintendo titles)). Even Halo I'd prefer on PC by far. Infact, I'd prefer all FPS for PC, gamepads are just a pain for them.
Other then that I do drastically need a new computer what can do much more then a console could ever, so IMO powerfull PC + Wii combo would have been best.
