In their latest brainwave on how to pry money out of people fed up with paying for upgrades they don’t want, Microsoft apparently are going to make the new version of Halo for PC only work on Vista.

Of course, this may also require people to upgrade their computers too as it is rumoured to require a lot more beef than XP does, though Microsoft are being very cagey about what they are for now. However, both AMD and Intel provide suggested processors. Then you’ve got to have at least 512MB RAM (though some would argue that XP really needs that) and a Windows Display Driver Model (WDDM) capable card, for which nVidia, ATI and Intel provide specs. Also check out this blog post by Steven Roddis who’s come up with a list of the individual specs.
