Ok i am finally moving to Windows 7. The only reason why i want to do that is because WindowsXP is limited to 4gb ram so i want to make full use of Win7

what is the fundamental difference between x64 and x32 and which one should i chose ?

Yes i know i will need to format my drive and i will lose everything i had installed on WinXP

More about : x64 x32

The biggest difference is that 64 bit support more than 4GB of RAM. Since 64 bit window support more than 4GB of RAM and you want that, you don't really have a choice but to get 64 bit.

32-bit is x86 not x32. The main difference of course is memory and memory management. Besides the huge increase in supported RAM, 64-bit programs can use more RAM than an equivalent 32-bit one can in a 32-bit OS. Not to mention support of 64-bit programs in general. There are lots more differences but that's about all I can think of right now without resorting to wikipedia heh.

No point in looking at any 32-bit OS if you want to run more than 4GB of RAM.

no, there is a 32 bit and 64 bit version of Window 7 only.

x86 refers to Intel or AMD CPU instruction set archetecture and should not be used in describing Window version.

The thing that x86 is related to 64bit OS is that the 64 bit OS require x86-64 instruction set to run. Intel and AMD cpu sold now are all x86-64 capable.
