Does it make a difference which version you are running?

The era of mainstream 64-bit computing is brought in by Windows Vista. Technically, you cannot tell the difference between a 32- and a 64-bit application under many situations. But 64-bit software provides you with more options and improved performance that 32-bit software doesn't. The design of 32 or 64 bit refers to the memory address length that can be referenced by the processor. The impact can also be seen on the memory to its mamimum that can be utilised. A recent trend has given much space to the 64-bit version and in the past three years or so, all new PCs have the 64-bit hardware. But with the introduction of Vista, the trend had shifted to mass embracement of the 32-bit version because the Vista could not handle the 64-bit version partition when it came to running programs and accessories like printers and scanners.

A 64-bit OS, paired with a large amount of memory, can make a big difference in 64-bit software. One of the most common consumer examples is Adobe's Photoshop CS4, but 64-bit endorse is becoming increasingly prevalent in applications that require to run a lot of complex, processor-intensive tasks. But all the application can not be made faster just by using 64 bit operating system because many of the software that are written and optimized today are for 32 bit. You need to install a software which is specifically optimized for 64 bit processing to take the privileges of any improvement in speed. The 32 bit software which you use is restricted to 4GB memory and if you want to take the full benefit of the extra RAM then you need to have a 64 bit CPU, operating system and applications. You can not run 64 bit operating system if you are using a very old software. If you are working 32 bit drivers then it will no longer work on 64 bit Windows 7. Now you need to discard poorly supported hardware as it will no longer be usable. When you try to run some 32 bit applications on a 64 bit operating system, it would actually work very slow. You will notice some degradation in performance.

In a nutshell, it totally depends upon the user what they use computer for. If your CPU is 64 bit capable but you are using older hardware, then it is better to stay with a 32 bit version. But if latest hardware and drivers are available with you then you should go for 64 bit operating system. The comparison and the choice is totally in the hands of the users and one cannot tell what exactly the user should do. It is in the hands of the user to decide what is best instore for him, taking into regard the elements of cost,compatibility and the current operating system running in the user’s computer.
