(Part 2 is coming soon...as will be an artical about how XP compares to 2K and 9X in games)
When I upgrade(RE: build new) computer in the next few weeks Im going to treat myself to Tribes 2, Max Payne, and a whole load of goodies (drool).
I post my proposed system specs on the Hardware page for all to see soon.
