Does 32-bit version of Windows OS only run on IA-32 CPU based PC?
the AMD64 chips. The 64-bit Windows versions can only be installed on
64-bit chips, they cannot be installed on the IA-32 (32-bit x86).
Note that there is also an Intel IA-64, the pure 64-bit Itanium
processor, in the Microsoft stable of products only specially designed
Server versions can be installed on the IA-64.
The main difference in the 32/64-bit chip architecture and the Windows
versions is in the amount of memory that the platforms support:

I remember that, when I do programming, windows XP (I use 32-bit
version) usualy shows message of "out of memory". Then I have to
extend the memory by increasing the virtual memory to the limit. I've
tried it. It is 4096 MB. It is very annoying.
Could you suggest me for the newer Windows and CPU?
ps. My computer is 7 years old with intel Pentium 4 1.7GHz and Win XP
version 2002.
Thank you in advance.

From Intel, there are the Core2 family of processors. Some are dual core
and some are quad core, meaning it is like having two or four processors,
only they reside in a single CPU socket.
The EM64T here, means the processor is 64 bit capable. This one is a
quad core.

AMD has Athlon64 X2 dual cores and Phenom quad cores. Also 64 bit capable.

For processor benchmarks, normally I'd point you to the charts on
Tomshardware, but for a change, I dug up another chart. Prime95 is
a program that searches for prime numbers, and the chart gives some idea
of how your P4 1.70GHz compares to some of the other processors. An
exanple of a decently fast dual core would be the E8400, which
costs about $170. It is 0.0111 in the first column of the chart,
while the P4 1.7Ghz is 0.0336 . That means the E8400 is about 3
times faster, even though the clock ratio is 1.76x. The E8400
dual core uses 65W of electricity, so should be pretty cool
running. Whether a dual core or a quad core makes sense, really
depends on whether the programs you run, are multithreaded.
Typically, multimedia programs are the ones that can split a
problem into multiple pieces, and have each core work on
a portion of the problem. If you do enough multimedia stuff,
then a quad might make more sense.
