This thread is a monster. I leave it for a few days to come back to over ten new pages! I want to keep up in order to help make the proper decision with regard to my build but I just can't find the time...
So if someone would indulge me with some advice, it would be hugely appreciated! First context: my 2011 27" iMac died a couple months ago. Whatever I get will be a dramatic improvement, so I can't really go wrong. I'd like to wait for Apple Silicon, but it's not going to happen. I need a machine now. I'm a data hoarder and I realize that I can go external (as I have been, by necessity), but I can't shake the desire to have it all on tap from a lickety-split SSD. I'm going 4TB, and I am allowing this irrationality this time around. I'm going 8 gigs of ram with the intention of upgrading it myself via Crucial to 40 gigs. That leaves me to two decisions-- the CPU and GPU.
As for the CPU... I typically go all out to stave off obsolescence, but in this case I'm thinking that the i7 would suffice. Everyone seems to be freaking out about the thermals on this machine. Is the i7 that much cooler than the i9 or do they both sound like hair dryers under load? Either one would be amazing compared to the 3.4 Sandy Bridge processor that I'm coming from, so going i9 would probably be a matter of vanity (more irrationality). The most intensive tasks I'd be throwing at my machine would be work with HandBrake. After that-- Photoshop and lots of it. Given what I've shared here, can anyone offer a compelling reason to go i9?
For GPU... I'm torn between the Radeon Pro 5500 XT and the Radeon Pro 5700. I don't know what the additional $300 buys me. I'm not a gamer, so it seems as though I can make do with less. The truth is, I don't know much about GPUs at all.
I figure I'll keep this machine for at least 5 years, and probably longer. I don't get the sense that the AS iMacs designed to perform at the level of today's higher end Intel iMacs will hit for three years-- but who knows? That's just my sense.
Thoughts?
