How much RAM do you need to Run Windows 7?
Microsoft recommends 1GB RAM to run Windows 32 bit and 2GB for the 64 bit version.
Suppose, you have 4GB RAM like I do, your Windows 7 32-bit will be able to utilize the available memory but, your 64 bit system can utilize it a lot more, maybe to the fullest. You will be getting full out of your RAM if you are using 64 bit system.
I have seen that Windows 7 64 bit works great with 4GB RAM and I am pretty sure, that if I add 4GB RAM additionally, it will perform better. More the merrier!
But, it was observed that while running high end games and memory sucking applications, performance was inhibited at 4GB RAM, and a friend who runs 8GB with similar configuration faces problems too, but not the magnitude as I do.
But, at the end of the day, it matters what processor you are running and the graphic card/graphic memory that you employ. Everything does not rest on your system RAM’s shoulders.
Make sure your hardware is compatible with 64 bits as most applications that we use on a regular basis are 32 bits, and they work just fine on a 64 bit operating system.

Within just a few years, thanks in no small measure to the plummeting price of memory chips, that balance will shift gradually. People are now trying out and getting comfortable with the idea of running a 64 bit operating system, especially on systems with 4 GB or more of RAM. [...]
