It's the AN8 nForce4 motherboard.



It should be fine.

Should whether the processor is 64-bit or 32-bit matter? If not,
when? If so, how so? In other words, should I go AMD or Intel? I
understand AMD is slightly faster for games, but what I'm more
interested in is the long-term utility of the 64-bit processor. By
the time 64-bit programming is mainstream, will whatever processor I
purchase be obsolete? I'd like for the computer to be functional for
at least two years, if not alittle longer. If I went 32-bit (Intel),
would it assuredly be obsolete, whereas with AMD not so much?


I would consider a processor with 64-bit support to be a slight
plus right now. At the moment, you're probably better off letting
64-bit CPUs drop the prices on processors without 64-bit support.
It's quite possible that by the time you want a 64-bit CPU for games,
the CPU you buy today will already be obsolete.



If you buy a socket 939 CPU and motherboard today, you should be able to
whack in a dual core CPU at the end of the year.

I suspect that the 939 socket will live for a while, with options like that.

And you believe this why? Any indicators that you can share by any
chance, or is it just a hunch? I went 939, though I don't have my CPU
yet, and I expect it to last a year maybe, but AMD has had a strong
habit of late changing pinouts like granma makes cookies and granpa
stinks up the room with cigars (At least my grandpa, who was a cool
dude, smoked stogies).

Dual Processors are going into socket 939 in under 6 months, that hardly
sounds like a socket thats gonna die soon.

When did Socket A come into existance? 5 years ago? And it's still going.

OK, so you've had socket 754 and 939 introduced. How long was 754
around before 939 came out? Not very long... there weren't that many
people who bought a 754 and were unable to do the research and find out
that it was gonna die pretty quick. So AMD made a mistake. However,
socket 754 will be around in the cheap market for some time too.

There's talk of a DDR2 CPU (new socket, over 1000 pins), but thats not
gonna be for a year or so.

Thats hardly that many sockets, look at what Intel are doing...

Too put it in VERY simple terms, It will matter when programs start being
coded for 64 bit processors and Windows 64 is released.. There arent many
out there right now, but until then, all programs run in 32 bit, regardless
of weather or not you have a 64 bit processor installed.

Unless you want to use an alternative OS (Linux, BSD, Solaris). Since
there are a lot of programs whose source is also available making
them 64-bit is just a recompile away.

Though I don't think many applications would really gain much for
recompiling into 64-bit versions. More memory space would be the main
thing.


P.S. Could you please not top-post?

That's the key difference between the availability of 64-bit processors
and the introduction of 32-bit and 16-bit processors. When 32-bit processors
and 16-bit processors were first available, there was already a huge base of
software that could greatly benefit from the additional capability. However,
there is very little currently existing software that can significantly
benefit from 64-bits processors. Few applications actually need to deal with
numbers larger than a billion, whereas many applications need to deal with
numbers larger than a hundred thousand.

I think David has a point, if it's speed your looking for but you dont
want to risk it use Parallel boards instead.

In the case of x86 64-bits, the real gain is to be had from the
additional registers, and the onboard memory controller (in some cases).
Also some unrecompiled 32-bit apps can gain from having additional
address space specifically devoted to them and not shared with the OS,
which now has its own address space well out of the way of these apps.

While for the most part that may be true for the majority of users, there
are applications where the added memory and address space would make a
significant difference, most notably where massive amounts of data requiring
extremely accurate calculations are slugged around. There are also a
significant number of businesses whose data mining operations, and on
occasion regular database requirements, would benefit from the extra hard
memory. Of course, a lot of those applications are already using existing
64-bit hardware and operating systems, so Microsoft and its toy operating
system isn't going to be making a great deal of headway there.
