I just want to know if it's worth an upgrade. CPU performance I don't really care as I wouldn't be using any CPU-intensive tasks, but GPU could matter as I might play some WoW and Steam games, etc. But other than the material upgrades, is the battery life better on the M3, is there more heat on the M3, and are there more software features that were allowed on the M3 (e.g. does M3 MBP allow more output like triple screens instead of dual screens, and allows HDMI 2.1, or something like in those lines?) I really don't know any upgrades that Apple didn't mention aside from the CPU and GPU so I would like to know. I tried Googling but no luck. I really like my M1 MBP for day-to-day tasks but I just wished GPU was a bit stronger for games and the battery life was a bit better as the battery drains a bit faster. Thanks in advance guys!
