“Coming from the original Pi model B, this is a massive upgrade. My gripes with this model of the Pi however are that there is currently no OpenCL support for this revision of the VideoCore GPU, I cannot run my 1440p monitor at any refresh rate above 60Hz (but apparently this board supports 4K 60Hz???) and when I do run this board at 1440p, the UI is significantly laggier compared to 1080p (at least, with Manjaro GNOME).”
“As with all Raspberry Pi 4 Model B 8GB I had bought it has superb engineer and performed the subsequent job I bought it for perfectly and worked with no issues at all. I'm not sure whether the purpose this time was to work with Argon M2 as a Server - Raspberry pi data transfer/share project that is due the next HackSpace or other superb Rpi project articles. Let you know when I have the file share working but my Raspberry pi to-windows share by SAMBA is working through my QNAP Windows NAS Drive.
Thank you for the excellence of the Raspberry Pi Foundation and even more so the availability of new Pi kit through Pi Hut first.

“So what can you do with an 8GB Pi. Why would you need that much memory? Well let me tell you. Because Linux can run on such small amounts of memory you can actually press an 8GB Pi into service as a native Linux hypervisor. That is a server which can run multiple virtual machines.
I would recommend using the Ubuntu OS for the Pi https://ubuntu.com/download/raspberry-pi/thank-you?version=20.04.2&architecture=server-arm64+raspi and the ARM version Ubuntu 20.04 for the guests https://ubuntu.com/download/server/arm
I see Raspberry Pi OS has just gained native SATA support https://www.youtube.com/watch?v=ZSx1BRwz1bs so you could just run your VMs on a SATA drive (don't store them on the MicroSD card) but I wanted to go a little further. If you have a shared storage medium like a TrueNAS you can use that to hold the VM files and have live migration. See linked video. https://imgur.com/a/iatMvVj
The upshot of all this I will be moving all my servers (monitoring, mail, search, dns, databases, nextcloud) into new VMs running on five (planned) Raspberry Pi 4 Model B 8GB.”
