So in other words, you'd want to have a Vega GPU with Core i7, right?
No. Not necessarily.
I highly doubt the regular iMac will come with the Vega GPU - not that you couldn't do it. There are i7 users who use the 1080Ti in their systems, even in their Hackintosh. Even though I'm not a gamer, I do wonder how much benefit some of my GPU accelerated apps would even get from such a beast.
The middle machine doesn't need to have the Vega or 1080ti equivalent - the RX 580 would be well enough as it is. If Apple did offer the Vega with an i7, sure, I'd consider it if came as a 6 or 8 core. If that i7 is a 4 core, then no.
Adding 32GB Ram, 1TB SSD and Core i7 makes the iMac 2017 pretty expensive middle ground machine.
Apple's closed system and inflated pricing makes this unbearable. Apple charges $600 24GB of RAM - to upgrade from 8 to 32GB - when you can get 32GB (2 x 16GB) of good DDR4 2400MHz sticks for $235.
It's a $140 difference between the i7700k and the i6850k. I'm sure Apple would charge $500 - yes, they'd have to swap motherboards in the BTO configuration. But it's "build to order"...
Apple essentially charges $600 for a 1TB SSD. Not terrible, since Apple uses Samsung chips, and the Samsung 960 EVO 1TB M.2 is $480.
Apple set iMac Pro's price so high, that regular iMac buyers wouldn't post pone their buying decision to next December to see if they'd buy that instead. Now they just lol at home who's gonna be so crazy simple minded Apple freak to buy a $4999 aio machine.
I've never said the iMac Pro isn't worthy of the $5,000 price tag. I'm not even one of those who is lolling at home thinking "who is going to buy this thing?". There are creative departments that salivating over this thing.
It's just frustrating that after waiting 8 years for a workstation from Apple, that they still haven't acknowledged the middle pro users. Or probably put a better way, the small creative/multimedia business users. Which is me - a self employed photographer that still crunches thousands of photos a year in Capture One Pro.
The iMac I have spec'd in the BTO configuration on Apple's website is $2,700. That's with 512GB SSD, 8GB of RAM, the 8GB Radeon RX 580, and the 4.2Ghz i7 for $2,700. All but the processor is perfect.
Add 32GB of OWC memory for $300 (half the price of Apple's 32GB of RAM upgrade), and I'd have 40GB of RAM in total, or I could upgrade to 64GB for $580 (a far cry from Apple's $1,400 64GB memory upgrade), and I'd be at $3,300 with 64GB Ram.
...or $3,000 if I only wanted 40GB of RAM.
Just add that damn 6-core i7 upgrade for $500, and I (and so many others) would be all over this.
Apple just assumes the 5K quad core is good enough for the small business users, which isn't true, 6-cores hits a sweet spot for a LOT of us, or you're going to pony up an additional $2,000 for an 8-core entirely closed system iMac Pro. Which also isn't true.
And really, the 100% closed system of the iMac Pro is the worst part of that whole deal. Buy a system with 32GB of RAM, then 2 years later you need 64GB of RAM, and now you have to buy a whole a new system, which will likely be another $6,500.
