All I want to know is how the new GPU's stack up against desktop versions....
All I want is the equivalent to the 6870 1gb desktop version. All the power I'll need for a long, long time.
Sorry, Charlie, the AMD Radeon HD 6970Ms featured in the high-end 27" iMac today are essentially underclocked desktop AMD Radeon HD 6850s. So expect slightly worse performance than that desktop card. It is better than the current Mac Pro's base ATI Radeon HD 5770, but not as good as the 5870 that you could upgrade it too, if that helps.
6970m = underclocked 6850, but close enough.
wow, am i the only suprised by quad core all over the place and 6970m as the gpu? thats a good gpu isnt it? how is that compared to the mobility 5850
isnt the 6970m the best mobile gpu amd has?
It's the best MOBILE GPU AMD has. It's a decent GPU, but for a $2000 desktop, it's kind of weaksauce, seeing as a $1000 Hackintosh could have the full 6850 that the 6970M is an underclocked version of, let alone a 6870. Still, it's the best you'll see in an iMac today while one of the chief design goals of the iMac is to be thin.
I think they are saying using the desktop 6970 would have been better than using the mobile version.
Also impossible.
iMacs are always going to provide greater "bang for the buck"...so if you dont need a mobile platform*, cheers to your new iMac friend
*Id really consider the possibilities of needing a notebook in the near future though. It would be a shame to need one and have to buy out of pocket. Stay well
PS: Just curious, why not go for the 27inch? The base 15inch is actually a tad more expensive than the base 27.
You can hackintosh a desktop quite easily; a laptop, not so much; given that, the iMac isn't all that great of a bang for buck, really. For Apple-branded machines, yes, the iMac will always be better bang for the buck than a MacBook Pro; but that's the way desktops have always been against laptops. Otherwise, paying $2000 for $900 worth of hardware and $800 worth of display seems a tad off to me.
And that's EXACTLY what separates perfectionist Mac users from ordinary Windows hobbyists...for the latter it's all about specs without any regard to battery life, design, noise levels and overall build quality.
Bottomline: I do NOT want to build my beige box, I do NOT want to worry about custom cooling, I do NOT want to infringe OS X's license by using it on unsupported machines and I do NOT want to worry about stickers on my keyboard or CPU.
Specs are what you are paying for. Otherwise it's decoration, and I'm sorry man, in this economy most people can't afford to spend money on "pretty".
Also, I think your idea of Windows hobbyists is a bit skewed. Most of them are after the same goal you are: to have the damn thing JUST WORK. Yes, an iMac is quieter than a Hackintosh, more likely than not. But an iMac has many many many more heating problems than a Hackintosh ever will. I see more iMacs coming through my computer repair shop than I do any other Mac. As much as I like the design personally and as quick as I will be to buy one once they finally get Blu-Ray (anytime between now and never), I'd be fooling myself if I didn't admit just how clunky they can be in practice.
I am placing an order, but would like to question the BTO
I will choose the 27inch version
3.4GHz Quad-Core Intel Core i7
4GB 1333MHz DDR3 SDRAM - 2x2GB
1TB Serial ATA Drive
Now the graphics is where I am stuck
Should I go for this
AMD Radeon HD 6970M 1GB GDDR5
or
AMD Radeon HD 6970M 2GB GDDR5
What is the 2G version going to give me more that the 1G can't handle.
My usage will be mostly Mac OSX, with the occasional boot into Windows 7 to do some stuff the Mac can't do easily. Game play is not likely.
Viewing photos is a must, and very little video editing.
I expect the computer to last a few years.
Also - where can you get a thunderbolt to DVI/VGA adapter from so you can run an external monitor?
1. Today, more VRAM will probably only matter if you plan on using your Thunderbolt ports to drive two additional 27"/30" monitors. Otherwise, not worth it. However, as minimum system requirements for things inevitably go up, having more VRAM might delay your need to inevitably upgrade from this machine to whatever is to replace it in 5-6 years.
2. You can buy a miniDisplay port to DVI (or VGA) adapter from the Apple Store. Same adapters work.
Im tempted to go for the maxed out 27" with the 2Gb GPU. Just after a few opinions on the Radeon 6970m. It seems a pretty high end mobile GPU that even the new Alienware 17x has installed. I get the impression that the new iMac maybe a worthy gaming machine underneath? Im pre empting the launch of Battlefield 3 and if I can avoid getting a sole Gaming PC for the job with a shiny new iMac then I m prepared to go for it. Any gamers out their have any advice or indeed experience with the 6970m?
My last Gaming PC was a Dell XPS600 with SLI nVidia 7800GTX's running BF2 so I know GPUs have cam a long way. Cheers.
It's equivalent to a mid-range card of current. It really depends. If you must have a desktop Mac, do it. Otherwise, I'd game on a PC desktop and get a MacBook Pro for all of your Mac computing needs; you get the best of both worlds that way.
To some (many) people, the all-in-one form factor is highly desirable. To deny that is foolish. It may not be your liking, but that doesn't extend to everyone.
Uh. You are way wrong about that. First off, the iMac is the only really successful all-in-one and even then, its sales pale in comparison to that of the MacBook Pros and the MacBooks. It may be your liking; but don't kid yourself, while popular, it's not as popular as you think.
