What CPU did you order?

I just maxed everything out, except for the RAM (32GB) and storage (4TB) - more will be added (384GB & 8TB)

Why 28? I was born on the 28th so I like the number, and I also don't want the hassle of installing a CPU myself.

With 25% discount, the cost becomes less painful @ $5,250 instead of $7,000 :)

how will you upgrade to 8tb?

How did you get a 25% discount?
 
More like add another 8TB - using Samsung 970 EVO Plus 2TB x 4 in HP or Sonnet (if I can get my hands on one)

Might do the Amfeltec Squid for 6 slots (waiting for them to reply to my inquiry)
I got some answers from them, what you wanna know? Price? $ 768.45 USD
 
My Pro replaced an iMac 27" from 2009 (4 core i7) which had been patched up with an SSD, more memory and various cooling hacks to keep the defective GPU from freezing the Ol' girl. I never felt it was CPU limited (the GPU was struggling with my CAD stuff though for sure.) I have 8-cores now, with the opportunity of a straight forward CPU replacement in a few years with some used high core count unit at a deep discount. I get that some people need to throw a ton of cores at things, but I don't have those workloads (and if I did would likely have time, I can wait...)

The whole point for me of getting the Pro was to ease keeping it alive for as long as possible. I've owned countless Mac's, but these days I am less focused on the latest and greatest, and more on practical long term (dare I say Siracusian) use. The iPad has also greatly impacted my usage and spending patterns, I am not one of those guys who insist that you can get work done on them, but they sure as hell can do everything else :cool:

I think that for the workloads I have, CPU's have been OP for decades, most of the technological progress has been around SS memory and GPU/High Resolution displays. I'm man enough to admit that HiDPI is mostly lost on my crappy old man eyesight, the old 27" still looked great to me. But I do a lot of 3d stuff these days and a slow GPU is really frustrating (as is a ton of fan noise.) I got the base 580 GPU too, I would have been tempted to get the 5700 had it been available at the time. But really I expect there will be cheap and high performance cards that will work great over the next few years. The base model provides a great foundation and is totally usable as it is. Very little downside to delaying the optimizations until they are really needed, even a used 580 will have a market, not like you are just burning money.
 
Woooow ok but it’s coming from Canada after all, so not much difference I suppose.

In the end, I decided to go with Amfeltec Squid. I just can't wait for the Sonnet and too worried about the HP (PCB version, firmware version, fan, etc.). Besides, it'll save an extra PCIe slot.

Now I just have to figure it out how I'm going to assign those 6 SSD blades and whether I swap slots with the Afterburner Card or not (it is occupying the last x16 slot)

I don’t know, besides showing off the insane speeds, what real world advantage is any speed beyond 6-8GB/s really gonna give you?
I’d leave the AB where it is.

I wanted to double the core count of my old 12-core for CPU-based rendering. Figured the extra 4 cores of the 28 wasn't worth the extra $1,000, and that the singe core speed of the 24 would be okay for single threaded tasks. Happy with my choice so far!

Good advice, but couldn't the same be said about the AB card?

I'm not really using it, I ordered it just for the sake of having it :)

Haha, well. I would still think if you use FCP or resolve that it’s a good thing to have down the line, more than insane ssd speeds.

so now that we know the majority picked 16c. Why is exactly that? What about this config gave the best bang for the buck?

It must be psychological . The previous generation MP topped out at 12 cores , so they had to go beyond that to justify the sticker shock of the MP7,1 .

I bought the 8 core knowing by hook or by crook , I was going to install something much better later . My MP7,1 is now a 28 core monster . She'll spend the rest of her life benchmarking this , that and other thing .

16-core is a great value. Its only $2000 more to double our core count without loosing much base clock speed. The nest step up is +$6000 for 24 core. I think this is a good example of diminishing returns.

My understanding is the 28-core is only 30% faster than the six core.
 
According to my test results , my 28 Core upgrade is a little over twice as fast as my factory 8 Core , with GB5 . I strongly suspect the benchmark is understating the punch of all those extra cores . The memory I currently have installed is not six channel optimized yet . Working on it ... and we'll see what relative difference that makes between the two extreme configs . These results are from the same Mac .

8 Core W-3223 .

Did you upgrade the CPU yourself? What did you pay for the CPU? New or Used?

Yes , I'm a System Builder . I build and service computers . It was an used processor from China I paid $4500 for . I going over it with a fine tooth comb to make certain its the real deal .
