The first 15" Retina MacBook Pro doesn't do too well because the Intel HD 4000 graphics didn't cope very well. Nvidia GT 650M is more than 2x as powerful. iMac won't have that issue since it will always be running off a powerful, dedicated GPU.

And saying that I have a mid-2012 rMBP and have never experienced any sort of graphical lag.

Same here.

But I would always go for the maximum CPU and GPU available. The base 5k imac is only an i5 processor. The last three computers I've had have been i7s, and I'm not going to downgrade now. The CPU upgrade looks to the untrained eye like a step from 3.5 to 4.0 (14% or so increase in speed). It's way more than that, as it's i5 to i7. Particularly for multi-threaded applications such as video.

With a beautiful screen like that, you want as much GPU power as you can eat.

Well the i5 is also quad-core so it should be no slouch at multithreading. True that it lacks hyper threading.

Did anyone yet find benchmarks for the m295x, like a 3dmark score or something?
 
You need as much gigabytes as possible to drive this 5k screen. If you're also adding another external monitor like myself, this becomes a must. Even 4gb of the 295X is not enough in my opinion, but we'll see the reviews first...
 
Hey everyone in here ... I am assuming the view on this is still very much in flux ... but I am the president of the Animation Club at my college, and we're allowed to make one "capital equipment" purchase request per every 3 years, and we are considering requesting a 5k iMac. Would you consider the m295x a large enough jump to be worth it?

We do Illustration with Photoshop (and Wacoms), 2D Animation with Anime Studio Pro, and Toon Boom Studio, and 3D with Lightwave and Modo. Probably throw some After Effects in there as well for final composition.

It's an extra $250. Yes, I would consider it. Faster is better when it comes to computers
 
For those of you that are purchasing the new 5k iMac and upgrading to the 4.0GHz processor and/or the M295X... what is your justification behind it? Are you a professional, gamer, for longevity, just have to have the best, etc...

What activities will you actually notice a difference between the two?

gamer, longevity, want to have the best...

tbh tho i'm having some buyers remorse right now and i'm thinking of RMA'ing the thing back...then will wait for Skylake.

I think if it made sense for me to wait, I would but right now I need a nicer larger monitor and I rather put that money towards an iMac which I'd plan to buy anyway.
 
I'm upgrading the GPU to 4GB to better power the 5k and an external 4k monitor.

I'm upgrading to the i7 because I'll be using this PC for the next half decade.

I would upgrade the ram, but Apple ram is a rip off. Will need to snatch some 1600 ram elsewhere.
 
Why so focused on VRAM?

I think Apple surely MUST know by now that the 2GB GPU is underpowered. It's why they offer the upgrade to a 4GB card (despite what seems like overkill from the perspective of running lower res monitors).

Why are we focusing so much on VRAM in the Apple community? It's really not what's bogging most the GPUs. Throw in a yotta-byte and it won't make a big difference. The amount of VRAM in these cards is picked based on the speed of the cards. A fast card can chew more data, so needs a stream of data coming at it quickly, whereas slower GPUs can't utilise that high bandwith and might as well wait for system memory. I want more stream processors, more ROPs, more TMUs, etc. Not more VRAM.

Nobody can really tell you about the GPU upgrade. The iMac is the first computer to use this GPU. That said, I wouldn't buy a 5k machine for these workloads without upgrading the GPU. There are a lot of pixels to push, and guessing based on the desktop parts, the difference between the two GPUs will make a difference.

Check out the Crucial RAM that I posted about it's the cheapest and best RAM at this point.

You just agreed with me.

Thanks! :)

because Mac Os is a vram hog. My iMac with geforce 680MX with 2gb choke when I plug in my Cintiq, its out of memory as soon as I try to work with a second application (usually maya + photoshop or After effects + photoshop) that use the GPU.
Yosemite uses about 1GB of vram on boot, with no apps running, plugging the cintiq brings it to about 1,3Gb of memory used. The 680 is still a powerful card but when out of vram is slow and unreilable.
I had to switch to Windows 8.1 for my work because of this.
I wish they went for the geforce 980m (heck even the 880m) because these cards usually have 8GB of vram that are ideal for such ridicolous resolutions and memory requirements of Os X.

I've decided to build a triple monitor thin bezel gaming pc. I'll be much more compatible for school stuff; I think I will enjoy my gaming experience more; and once I sell my mac mini then I'll have funds to buy games.

So I'm going to refuse the package, which is still stuck in China somewhere...

More than 2x as powerful?

Almost 3 times as many pixels to drive.

It will be fun to watch from a safe distance.

Do you really have that much doubt about it?

I ask because I'm likely going to pick one up. I have the MacBook retina with the dedicated NVIDIA GeForce GT 750M 2048 MB. It's able to power a 1080 monitor, the built in retina monitor as well as an external 4k display.

Based on this, I do think the new iMac will be fine running 5k on its internal monitor. Where I'm concerned is both with heating, as well as external displays.

Most likely, I feel that there will be some lag running a 5k and 4k monitor off of the new iMac, both at 60Hz respectively. I rarely game, but if I did, gaming at 5k would probably produce a lot of heat.

My MacBook Pro only has 256megs of VRAM, and when in a pinch I run Final Cut on it. Doesn't run that badly (I mean... It does relative to proper equipment, but all things considered. I at least don't feel that bogged by VRAM)

Hey, if you really need 5K, knock yourself out.

Just remember, "Pioneers are the guys with Arrows in their backs".

Apple has been making iMacs for years. There's 2 problems I foresee:

1. gfx cant keep up with display buffer
Possibly. But if my rMBP can output to 4k then this iMac can probably do 5k. Just get the 4GB vram model to be sure.

2. Apple may have screwed up something with the timing adapter for the monitor.
Apple care.
