Will upgrading to 64bit with 4 gigs ram improve fps in games or won't there be a difference between 32 and 64 bit.

64 bit does use more resources, however if you have the 4 gigs of ram already then it will help quite a bit as Windows will be able to recognise the other 750 odd megs of ram that 32 bit can't.Quote:

I haven't seen any noticeable difference in performance between the two.Quote:

Windows 7 is plenty stable.Quote:

Not true.
Applications can only use memory that Windows can assign to them. If Windows cant see it, neither can they. The other portion of your memory is not being used at all, not by anything.
The reason for this concerns memory mapped IO and whats called an address space. An address space refers to all memory that the computer can access. It normally means main memory, except when memory mapped IO is involved (and it always is on modern computers). One quick note, programs have their own address space which is distinct to the windows address space. A program's address space is also smaller than the windows address space, since it must be able to fit into the windows address space. The biggest unsigned number that a 32 bit computer address is around 4 billion, which is why a 32 bit computer can access 4GB of memory, at maximum. However, this is not what Windows sees, and memory mapped IO is the reason. Memory mapped IO assigns a portion of that address space - which normally points to main memory - to your other devices, such as your sound card and your graphics card. This is convenient for programmers because it means we only have one address space to work with, but it means our 4GB address space has to be shared with both main memory and all devices. Obviously, since we need devices, main memory must shrink. This is why main memory becomes reduced in size.
These days, there is no reason to use 32 bit at all. You should never use it, even if only have 2GB of RAM right now. You'll just run into headaches when you eventually expand your memory. I've been using 64 bit windows since the Vista days, back in 2007, and never had any problems with it.
64Bit with at least 4GB ram memory
There isn't really much reason to not install 64 bit. Most all systems built in the last 7 years or so support it, and eventually you will need it.
