I'm looking into getting a g5 mac soon. If the new models aren't released within the end of the month or beginning of april (which many speculate that they are) then I'll be getting a 1.8 g5. I'm just wondering if I should go for the dual processor or single. The most extensive thing i'm going to be using the computer for is video editing and playing some games (world of warcraft when released, halo, etc...) I realize that dual processors help out video editing, but how much of an impact do they have on gaming? thanks for your time!
