You’re exactly where I was. Lol. For the longest time I was sure I was going to get a 3060ti because the 3070 was just too expensive. Then as prices started dropping and secondhand cards were getting so much cheaper, I was inclined to open up my options. After reading a lot, I decided that the extra vram would serve me better for a long run with the card, especially since I was generally finding the 6700xt going for less than the 3060ti and 3070 on FB marketplace.
And as you said, the recent business practices by Nvidia definitely weigh heavily.
Yes. There is a legit plex app on fire stick and roku. It comes with free live TV and on Demand content, but you can also run your own server on your network with your own downloaded content. If you have an IPTV service you can stream that through plex as well.
Note that Jellyfin is a similar app/server that works the same way and is totally free. Plex is also free, but there are additional features behind the pay wall like GPU decoding, PVR service for IPTV, and others.
