The 1070Ti doesn't have the hardware necessary for DLSS, which makes a huge difference in performance for gaming.
Also I was using the 3050 as a low-cost example (it's what I use). My roommate uses a 3060Ti and that thing easily handles every game she's thrown at it.
I can guarantee you'll get more bang for your buck going with Nvidia just due to the fact that so much compute software requires cuda (blender, machine learning, any sort of engineering simulation software). Nvidia drivers are just less of a pain to deal with as a developer, since they're less strict on error handling and syntax.
You can get a 3050 on amazon for like $150 now, which is more than enough for most games.
Plus DLSS is still miles ahead of FSR in terms of quality and efficiency.
Yeah I'm pretty sure a raspi 4 is up to the task. I ran a 512 GB jellyfin server on a raspi 3 for a few months, and the only issue was with transcoding video/audio (raspi doesn't have the right hardware acceleration for that).
Never used nextcloud, but yeah you'll probably want to update to 64-bit raspi os
I use both, since they do different stuff. I actually remote into my servers with wireguard, but I like to install tailscale as well as a backup. Since each device gets a unique tailnet ip, I can usually still connect even if I've fucked up some network config that breaks wireguard. ((If this is a security risk, someone let me know because I have no clue what I'm doing tbh.))
Plus tailscale lets you easily see what devices are connected to the internet at a given time.
Raspbian (modified Debian Jesse) on a raspberry pi 2B (which I am still using over a decade later to host some discord bots). Also now using Debian 1Bookworm on an old optiplex as a media server.
Looks like the color space is being read improperly somewhere.
Not sure if this will fix your problem, but you can set the color space of an image with the ColorSync Utility (should be preinstalled on macos). Open the image (File > Open), and at the bottom of the window select Apply Profile. Try experimenting with profiles in the second drop down box to see if the problem goes away (they shouldn't change the way the image looks on your screen).
sRGB should be compatible with everything, but it's old and doesn't have a very wide gamut. For your image it should be fine though.
I stole the idea from you! And I'm not giving it back
