I'm using 32-bit operating system since I've my laptop. I've never used the 64-bit operating system so I'm much curious about this that if I upgrade to 64-bit still my pc will give me the same performance. However I've checked about my hardware from this question. I don't know about those result that what they are saying? So I'm here for little help to know that is there any performance issue after upgrading or not?
In common usage, the reason to go 64-bit is to make use of more RAM (memory) in your system.
In Windows, 32-bit is limited to a little over 2GB of RAM available to programs, while 64-bit is virtually limitless. To benefit from it, your processor must support 64-bit. The D.E.P. and virtualization are not related to performance in common desktop usage.
So, since Windows 32-bit already supports a little over 3GB of RAM:
It is unlikely that you'll notice any difference in performance when moving from 32 to 64bit.
The note about no hardware virtualization can be ignored. If you didn't miss this feature while using your 32bit operating system, you won't miss it with 64bit either.
