Sure, its safe, just dont have any illusions about a magical speed boost from 64 bit cause the software just isnt there yet, most of it is still 32 bit.
If you have starcraft your going to have problems since parts of it are 16bit and X64 OS wont support 16bit at all. And they are still beta testing X64... There hasn't been a final version released yet or it would have been shown on my home page.
It's retarded why they don't just include a 16-bit subsystem into Windows 64. Even if there is a performance hit for whatever reason, surely, they can give the option to the user to enable it??.. :-\
It would be nice, but if battle.net and blizzard plan on keeping starcraft around much longer there going to need to remake it or make a huge ass patch to rewrite the code of the game....
I wanna know how much they want to charge me now, because to get it i have to "exchange" my XP pro copy for that damned thing..... Then they ask for a credit card number and at the bottom saying we will charge you once your item has been shipped.
EDIT:
Found a copy on newegg, but based on reviews ill wait about 2 years before i upgrade....
