This is one of the most common questions that I get from people who are looking to buy a new computer, should they get the 64 bit version of Windows or the 32 bit. To make this long story short, if you are looking to run over 4GB of RAM in your computer then you will need the 64 bit version, if you do not care about the amount of memory then I would stick with the 32 bit version.
Note that for most people 4GB of RAM will be more than enough to run all of their applications, also remember that having more memory does not mean that your computer will run faster, all it means is that your computer will be able to run more applications at the same time. If you are looking for more speed you can still benefit from running a 64 bit OS and hardware however I would look for a faster processor, for example anything with at least two cores running at 3.0 Gigahertz will give you excellent speed.
If you ask me (IT Professional)I would get me a computer with the 32 bit version of Windows (less compatibility issues), 4GB of RAM and a processor that runs at least at 3.0GHZ. This should be more than enough to play games, browse the Internet and do office work.
However we know that technology changes fast and even though these specs worked great a few years ago, now I would highly recommend that you get Windows 10 Home or Pro with 64 bit, also 8 GB of RAM and an SSD hard drive are a must! These specs will allow you to have a great Windows 10 experience at an affordable price.
