An extraordinarily good comeback. Bravo. Encore! Encore!

the PC!
Don't you ever play anything else MORON?

And btw stop CROSSPOSTING your CRAP STEAM INFECTED posts to others

You can tell it's getting round to "that time of the month" can't you?

Yep. I'm using a single chip (AMD64 3700+), and it handles all of the
latest games without a problem (even ET:QW). Eventually, games will
actively use the second core (physics and whatnot), but until something
comes of that, and in a game that I am actually interested in, I'm sticking
to my single core.

I feel the advantage of double core is that the switching between the
running programs occurs more smoothly (e.g. switching between the
running game and the windows desktop). This is a whole new experience.
With all the other "houskeeping" tasks redistributed by Windows to the
second core, the first core can concentrate entirely on running the
game (I presume), and the 1.9 GHz processor can be equvalent to 3 GHz,
which is already good.

I noticed that the players of Half-Life 2 (and of other Steam-
distributed games) have a quarter of their machines with dual cores,

dual-core is *definitely* the way to go so you made the right choice - no
question about it.

HL2 currently doesnt utilize multicore CPUs well but that will change in a
month or two.

Valve are working on adding *hybrid threading* to the source engine which
will make good use of both cores.

Most games that currently support multicores only use coarse threading -
offloading one or two functions to the 2nd core. ie the 1st core does the
rendering of graphics (90% of the work) and the 2nd core does physics and
sound (10%) - in this case you only get a 10% boost in performance at best.
Valves' hybrid threading approach will yield a much better increase than
that.

whats the rest of your system? what RAM and graphics card do you have?

I recently went from a AMD64 3700 (san diego with 1mb L2cache) to a x2 3800
(socket9390 and games performance is about the same atm. Windows
multitasking is however a whole lot better and worth going to dual-core for
all on its own IMHO.

The only ppl so far to add *real* dual-core support to their engine is ID
and latest patches for Doom 3 and Quake 4 add a significant performance
boost.
http://www.firingsquad.com/hardware/...ance/page4.asp
that should work for ET:QW too of course.

I play DOD:Source myself so Im looking forward to the hyrbid threading patch
that should be out soon.

That'd be MHz, and no, it's not where the performance rating is derived
from. It's quite an easy matter to google this.

No, he's saying it doesn't utilise it at all. It's written to use a
single core/single CPU, and that's all it will use.

Only one core is running the application, yes.

You really need to do some reading as to what the 3600+ really means.
It'll explain to you why you may be in error here, too. Speed in GHz is
no longer a valid measure of CPU performance. CPUs are changing, and the
refinements in how they work are what is brining performance up more
than just raw speed. Use benchmarks to compare CPUs now, not GHz.

Have a look at how your new CPU compares to your old CPU in gaming
benchmarks. There are too many other factors, such as RAM type and
speed, motherboard, etc, to make the conclusion you're heading towards.

Ari
