I've owned SMP machines in the past and often found it more useful to force CPU affinity of CPU-heavy tasks to a single processor, as Windows 2000 (which was current at the time) by default had a habit of swapping it between chips, resulting in a lot of cache-dirtying....
However, you could see some significant improvement in processing time on some non-parallelizable cpu-bound tasks.
I came to the opposite conclusion....
Running many compute-bound single-threaded benchmarks and apps - I saw how NT (pre Win2k) would balance across CPUs (that is, a "100%" compute-bound job would show each CPU running at 50%).
However, setting affinity so that one CPU was 100% and the other was 0% had no significant effect on the run times. (And by "significant" I mean statistically significant - I literally ran hundreds of runs in each configuration.)\\
By the way, with Win2k3 (and XP 64-bit, really the same system) you see much less "balancing" - a single-threaded app will stick to a CPU for much longer.

I'll probably come of sounding like a jerk and opening a HUGE can of worms with this, BUT...
...Why do we constantly have to place a line between men and women, black and white, American and everyone else.
You do realize HIV effects women differently than men? It also effects children differently than adults.
Do yourself a favor and do a quick google on how much money has been spent on HIV research and prevention for children and women, compare that to men with HIV. Then do a search on children/women with HIV and mortality rates compared to men w/HIV.
We live in a very sexist society. HIV research was never funded or taken seriously by society at large until heterosexual white men started to develop AIDS.

And I'm thinking... why?! 10 years ago BeOS had this down pat. The whole system was multi-threaded and multi-processor aware from the kernel all the way up through the user interface including the system services used by all native applications. It was amazingly responsive and was reported (in major publications) to gain as much as 60-70% performance by having a second CPU. I realize MacOS X is based on some old NeXTStep code which was not made for multiple processors, but come on! This is the 21st century and Apple's been selling dual processor machines for about 5 years now.
Anyway, this is great news. I'd been drooling over the new iMacs since they were announced and wondering how much I might gain by upgrading from my 2GHz G5 PowerMac. It's very enticing.
Well they were selling them back in 1996 so you might want to add 5 years to your 5 year statement. You could buy dual 604e in the 9500 and the 9600 too I think.

I see people still talking about big announcements at the Paris expo. Considering there will be NO keynote of any kind I find it unlikely.
Agreed. I think there will be 'quiet updates' of the Mac range in the coming weeks, plus a 'Special Event' or two in the coming months for the announcements of the new iPods and Movie Store.

Don't get me wrong, I would welcome a new enclosure but I think that allowing the prospect of one to be the determining factor in the purchase of a machine is ridiculous. As much as I would LOVE to have a gunmetal colored mbp, if it came out tomorrow I wouldn't be upset that I have a silver one because I truly do love my machine. Apple will always continue to innovate and release new products, and IMO now that they're using intel chips the rate of obsolescence will increase (in terms of harware and performance more than appearance).
To get a new design and enclosure is always nice. Apple has been doing amazing designs in the past years. For sure new enclosures will look nice.
The thing is, at this time after the whole Intel transition, all the current enclosures stayed the same (except few changes on Macbook). So, I would not expect anything different anytime soon. I think the current look is great in all Apple hardware line up. The only place I thought it could have a change was on the MacPro, because the G5 needed such a large enclosure. Apple responded keeping the same design and just adding more features that before was not possible under the G5 chip. That makes me believe they will keep the same enclosures for awhile.
I agreed that subtle improvements are welcome and they probably will happen. But if people are making their buying decision based on a new look coming soon, I think they will wait quite a bit and get disappoint.

I'm looking at getting a new iMac fingers crossed for the following:
- Bluray (I know... but it would be nice)
- Thunderbolt
- USB3
- AMD Radeon HD 67XX-68XX with up to 2GB RAM (it wont happen though :()
- Space for 2 HDD (I know, again it would be nice for two internal drives)
- i5 and i7.. Hopefully no i3 in the line up.
- Up to 24GB...
Again if I can't get an iMac with beefier video card it looks like another Alienware with Linux...

This article points out that Microsoft has a hard time with large numbers of pirated copies of Windows being used out there. It made me think that there are probably people knowingly running prated copies of Windows, who visit sites like macrumors to try and champion their beloved Windows. LOL. I'm sure it happens.

if you have marantz speakers...... you have 40 dollars.
True, but if you've just spent �450 on the receiver and another �100 or so on speakers you'd maybe resent having to shell out more for AirPlay.

Wow, the dual screen output is what could some day push me over the edge. A 27" display + 2 27" Apple screens either side sounds pretty nice. Still not enough to make me part with my 30" ACD right now though.
You do realize you can do almost the same thing (not sure about resolutions) with USB2 displaylink adapters?
My lowly 2007 Santa Rosa MBP can handle this fine with one 22" monitor using the old EVGA UVPlus... I even run it over a hub that also does keyboard, mouse and iphone cradle. Slight delay, no stutter, nothing. videos play fine (never tried full screen, but it's my work computer, so no need for that).

and what exactly is the gapless playback...I guess I missed that. Im a little disappointed by the conference...i mean the new iTV isnt even available until next year...blah
"Gapless" means no more little micro-pauses between tracks. You'd only notice it if you were listening to a live album or something like "Abbey Road" where the tracks segue into one another.

Until Leopard is out we wont see the true value of these babies. Also by then some of the apps will take advantage of the muti-cores and multi-cpus, and the changes to the OS will allow applications not written for more than 1 core to take some advantage also. So like I said Leopard will be the one showing the true potential of these babies. Can't wait!!!!!!!:cool:

I am going to say that I am in favor of not having Apps whose only purpose is to assist people in breaking laws and also increase the possibility that someone innocent will get injured or killed because of the use of such an Application.
In other words if there is no legitimate use for an App other than to break the law and put people's lives in dangers, I think it is reasonable to ask Apple to review their policy on such things.
Anyone who drives drunk these days has major problems. Anyone who uses a phone/tablet app to assist them in driving drunk is a complete arse and I can only hope bad things happen to them.

Playing around with a Mac OS X Leopard system and noticed that default apps can be modified without authentication by admins unlike Snow Leopard where authentication is required.
What exactly do you mean? Do you mean changing the default app for opening a file type, using the Get Info window? Or do you mean some modification to the app itself? If the former, it works the same in L and SL. I haven't tried the latter yet.

It's interesting. Every single poster here clearly disagrees with your actions (which are undeniably illegal) and your justification (including your improper blame on the woman driving in front of you). And yet, it's everyone else that must be wrong, not you.
Like I said, it's interesting.
