If i purchase the digital gw2 edition

if i where to purchase the digital gw2 edition, what happens if I needed to get a new computer, would i be able to install it again ? wish this game was GW2 Gold out this month not next month, theirs no good mmorpg to play atm to keep me goin another month. Why is it that Guild Wars 2 gets a release date just right after I move to a new city and wont be able to set up internet and stuff in time? once you purchased gw2 you can install it on as many computers as you like, although you can only be logged into your account from one computer at a time. Guild Wars 2 Power Leveling will be on Crystal Desert! Glad that Crystal Desert was not removed. Will this update have DX10 support? Or has it already been added? I missed the last beta weekend because i was out of town. Id like to see DirectX 11 at some point, that beautiful water needs displacement.
