Gears of War and dedicated server hosting

Hey guys I have a small query. I’m planning to buy Gears of war for my Windows XP computer. But before I order the same I would like to if what is its system requirements and is there any dedicated server support ?

Thanks in advance.

Guild Wars was launched in April 2005, followed by its first two expansions Factions and Nightfall in 2006. A new expansion, Eye of the North, is due for release on August 31. Guild Wars 2, a completely separate game, is also in production, slated for sometime in 2008. Since Guild Wars 2 will not support characters from the original Guild Wars games, Eye of the North is intended as a bridge between the two, with the Hall of Monuments allowing players to save weapons, armour, and other achievements for retrieval in the sequel.
