Should I install 64 bit operating system ?

The FX-8150 processor you have on your computer is an 8-Core 3.6 GHz AMD processor. Since you have AMD FX-8150 Zambezi 8-Core 3.6 GHz processor plus 4 GB RAM, it is way above the requirements for 32-bit Microsoft Windows 7 and also way above the requirements for 64-bit Microsoft Windows 7. To be able to install any 64-bit Microsoft Windows, your hardware should support 64-bit architecture.

Meaning, both your processor and motherboard are in 64-bit architecture. Fortunately, when I checked your processor, it says there that the AMD FX-8150 Zambezi 8-Core processor supports 64-bit. So, since your processor supports 64-bit operating system, your motherboard also supports 64-bit system. You won’t be able to use your computer if your motherboard is 32-bit. Since you can use it, therefore both your processor and motherboard supports 64-bit.

This means you can install 64-bit Microsoft Windows 7. For you to be able to install 64-bit Microsoft Windows 7, you should have at least 1 GHz 64-bit processor, 2 GB RAM, and 20 GB free hard drive space. The big advantage of installing 64-bit operating system is that it can support up to 17 million TB RAM.

So with your 4 GB RAM, the operating system can fully utilize the full capacity of the physical RAM when you use 64-bit Microsoft Windows 7. While if you are using 32-bit Microsoft Windows 7, the operating system is only capable of using up to 3.25 GB of the physical RAM. The remaining 0.75 GB is gone wasted and not used.
