well i think the best thing 2 do it 2 wait and see if it is the 64-bit verison ur getting, but coz of the price of it, i think that they will just send u the 32-bit one, they want you 2 buy the 64-bit one thats how they r going 2 get the money, but yeh wait and see which version u get, and if its the 32-bit one, u mite aswell stay with that until more programs run as 64-bit, coz it will take time for everything 2 become 64-bit
