I just bought a 27" i5 Quad Core 2.66Ghz iMac upgraded with 8GB RAM, and have to say I'm more than blown away with the performance. As a professional musician and doing a lot of work in the studio, this computer is more than enough to handle the tasks I do. The LED 27" monitor is astoundingly sharp, and fit and finish top notch. Anyone else have the i5 or i7 iMac?

iMac 27" i7 here, also with 8GB at this point (and an additional display connected).

I'm still waiting for the price of a 16GB set to come down a bit, although I could put it to good use even now.

Both the rather fast quad-core CPU and especially the display were my reasons to go for it – I had never considered an iMac before, but after a good two months in heavy use I must say it does indeed fulfill my expectations completely.

Very pleasant to use, no problems.

The much higher resolution relative to my previous primary display helps a lot keeping more information at hand in more complex working environments. Even with Exposé, nothing beats actual screen resolution.

Yeah you know the i5 and especially i7 are turning faster numbers than even the current MacPros. Obviously due to the new i5 and i7 processors not yet available in the MacPro. The 27" LED screens are absolutely marvelous. No offense to PC users, but Mac is a step ahead than anything else offered in the iMac class as a total package.

This thread has a very different main topic and the controversial stuff has already been done in the other thread at length so there really isn't much of an incentive to rehash it here.

You really are running enough applications that you need more than 8 gigs of ram?? Damn, that's some intensive computing. I've got 4 gigs on my laptop and with my 32-bit version of windows I can only access 3.2 gigs worth, and that's plenty for my needs, but I'm hardly a computing professional.

It's all a bragging point these days. Really, for bare-bones computing, you can use 1GB of RAM, and you'll be fine. Hell, my FS rig only has 1GB, and it can run FSX pretty decently.

I'm sort of curious as to why Apple provides an option for 8 or 16GB of RAM. It's not like you're going to be playing Flight Simulator on it (without Bootcamp). I'd be intrigued to find out what you'd have to do on an iMac or Mac of any kind of use up all 8 or 16GB of the RAM.

THis is for us folks who do video editing, run photoshop, illustrator and others all at the same time. We need every bit of power we can get.

And we don't want to spend AUD$11,000 on a Mac Pro. I've got a 27 inch iMac Core i7 920 8gb 1TB machine coming on Monday. Can't wait. I'll also have an additional display connected.

Actually, the current MacPros use chips based on the same Nehalem architecture used for the i5 and i7 chips in the iMac.

Try running virtual machines. I've 8 GB in my MacBook Pro and 24 GB in my desktop, and I still would like more to play around with.

Frequently. Right now I have 10 major and 7 minor applications open with a total of 69 windows across two monitors (2560*1440 + 1600*1200), plus various background processes. And it's often more than that during work.

At this time I don't even have VMWare running, which adds complete Windows or Linux installations with their own additional resource requirements on top of that.

Like Windows versions since Vista, Mac OS X has always used a compositing display engine, so it uses additional RAM for keeping the graphical window images in the background (either on the graphics card or in CPU RAM).

And also like newer Windows versions, it uses any RAM that's left over as a harddisk cache to speed up file operations.

With everything that's going on at 8GB RAM the system will still start to swap virtual memory to disk at some point. And if that happens more frequently (it does more than just occasionally on my machine), expanding RAM will usually provide a real speedup.

So upgrading to 16GB would indeed make my machine faster especially when it matters the most. The bigger DIMMs are just still relatively expensive, so I'll probably wait until the expected speedup starts mattering more than the price I'd have to pay...

No.

Aero is Microsoft's copy of Aqua, the user interface layer of Mac OS X (and even through its name clearly aping it – it seems Microsoft can't create anything original).

Quartz is the graphical 2D drawing framework which also provides the compositing functionality which Aqua uses, and all these parts have been in place right from the start of Mac OS X in 2000.

Quartz Extreme was merely the first version of Quartz which used hardware acceleration, actually not changing anything significantly apart from increasing performance. Before it, all the compositing was done entirely by the CPU, but it was already fully present.

The conceptual step in user interface design and inner functionality Microsoft took belatedly with the introduction of Windows Vista just mirrored the introduction of Mac OS X 10.0 six years earlier.

Yeah I firmly believe after using a Mac personally for 15 years, and having a father who has used a Mac since 1985, that much of the brilliance is in the OS. OS X 10.6.2 (Snow Leopard) is just brilliant.

On a side note, any of you Mac users tried the sampling of Google's Chrome? I still prefer Firefox 3.6 as my browser.

With Chrome I don't really like the amount of information it feeds to Google (naturally, since that is their business model). And I have the WebKit engine with Safari and other browsers already, so I don't see much of an attraction for me.

The graphics card part didn't happen till Quartz Extreme, yet you claim that OSX always had it.

Even then, the backing store wasn't moved completely to the video card until 10.4.

It used 3D hardware acceleration, before that compositor still had access to 2D acceleration features when writing to the frame buffer.

This is still very different from Superfetch used in Windows. While, OSX caching makes reload times fairly quick, Superfetch also makes initial loads quicker. Just as an example, I upgraded both my MacBook Pro w/ 8GB of RAM and one my Win7 PCs with 8GB of RAM to SSDs (actually 2 SSDs in RAID0 on the PC). In terms of initial app load time, their was a huge difference on the MacBook in OSX, whereas on Win7, the impact of the SSD was only really noticeable in terms of boot time and other file operations.

Well, I use Chromium nightly builds and they're a bit faster than Firefox. I still run into sites with compatibility problems though, so I have to keep Firefox around. I don't use Safari because it doesn't have the plugins I need.

Just read my actual posts again.

I was talking about CPU RAM, not graphics card RAM.

And graphical backing stores in CPU RAM have been a reality since 10.0 and still are. They are the primary reason why OSes with compositing graphics engines use much more CPU RAM than their respective predecessors, but in return they avoid the ugly redrawing of newly exposed window regions and usually provide a smooth, real-time UI behaviour.

My bare bones computing started with 64K of RAM - upgraded from 16K.

Now we're talking GBs - the MBs days are long gone.

With a TB probably not that far in the future.

As for the new iMac, I'm still drooling over it. Just like I'm drooling over the new iPad due out soon that my wife has already said I can't have (even before I had a chance to mention that it would be nice to have) so all I can do is have plenty of paper towels around to wipe off the drool.

I can't say anything about Entourage as I don't use that. Since Snow Leopard (which your new machine should have), Apple Mail can also access Exchange accounts directly. It may be a viable alternative if you can't get Entourage to work with Microsoft's support (if not in any case).

As to Premiere, I don't use that either, but I would normally expect that multi-platform Applications should be able to read files of the respective other version. Or are they widely differing version numbers? What does the manufacturer support have to say?

As I've said before, when you frequently have relatively dark images on the screen it will depend a lot on your lighting situation whether the reflections can be a problem or not. With almost always dark text on white backgrounds I don't have a problem with it, but for image or video processing a separate matte display can be advantageous, especially if your workplace is badly lit (meaning the light coming from your back in this case).
