I was leery of getting a 64 bit system when I bought mine. Glad I did. This article does help with understanding what is what with them. I do appreciate it.

How do you explain this?
Launching an application not adapted for the 64-bit platform might on the contrary cause great performance loss depending on the specifics of the architecture of the processor being used.

Taken from What advantages do 64-bit processors have over 32-bit ones?

Regarding the OP, interesting read that 64-bit has performance advantages in computation, however these advantages are still due to increased addressing space of some sort or another, the computation takes just as long.

Indeed. The processor speeds will always be the same, the advantage lies in the extra addressing space and coding.

And because of better architecture, the coding of many subroutines can be made in such a way that it will be executed much faster (not because you can have much ram).

Changes in CPU architecture are specific to the number of bits your using for address space?

64 bit machines are only faster if the program running takes advantage of the additional width of the data buss. That is almost always a function of the compiler used to create the executable though how the program is coded (what kind and width of variables are used) also has an impact.

Win 7/32 to win7/64

Can I install win7/64 over my existing 32 bit OS or do I need to remove the 32 bit system first?
Any help you can give this babe will be much appreciated,thanks.
