I created a thread, but I guess it is getting lost in the slew of posts:
I have a 27" late 2013 iMac (3.5GHz quad-core i7, 8GB RAM + 2x8GB user-installed, 1TB fusion Drive and NVIDIA GeForce GTX 780M) that just came out of "repair". It basically died in March but because of COVID, I waited for the stores to reopen to get it checked out. They got it working, but the issue is the motherboard and they can't say how long it'll hold on (and it's 800$ to replace it, which at this point isn't worth it for a 7yo computer).
I'm a video editor and I do photography, and until problems with the HDD and then the motherboard, never had much issues (even with 8K raw files, I just did proxies. The only thing that caused hiccups was when I tried to stich really big panoramas in Photoshop and it would run out of RAM and HDD space). Because I had a NVIDIA GPU, to take advatange of CUDA, I was stuck at High Sierra, and the whole thing was a mess.
So now, with today's refresh, I'm tempted to upgrade. I've been working on the office's Windows PC (now in my room) and that thing isn't all that. For some reason there's input lag when working in Photoshop, and the fan runs 100% of the time. My room is always at least 3-5 degrees hotter than the rest of the place.
With the Apple Silicon/redesign coming, I'm hesitant though. I'm thinking of getting a "modestly" spec'd iMac (Standard glass, 3.8GHz 8-core i7, 8GB RAM (and buy a 2x16GB upgrade seperately, for 40GB total) Radeon Pro 5500 XT, 1TB SSD storage). With the student discount, it'd be CAD 3 675$ with the AirPod Pro. Then I'd also have the option of selling it when the redesign comes out.
Any thoughts? I have my cursor ready to click on Checkout, but I'm hesitant...
The new Intel iMac will be a significant boost for you.
So if you buy a £2500 Tier 3 spec iMac it will double as a £2500 PC.
You can always buy an AS iMac when it comes and run both side by side.
The 8 core 5500xt is great value.
