remember Acer Nitro and Gigabyte G5 or was it G6? has the best bang for buck for RTX4060, they usually price between rm4,300 to 4,600 last year.
but please remember to check reviews for the GPU watt. anything above 100w for the GPU should have decent performance . and also review on cooling.

yes you are right, the Gigabyte G5 only 75w which for a RTX4060 is crippling.
not too sure about Acer Nitro fan being noisy.

weird that the LOQ on website does offer RTX 4060 but not in config.  and it is a 115w some more...
shopee seems to listed a few LOQ with RTX4060 around price 4.3K-4.5K , hope that helps.
my best advise is maybe you can try to call Lenovo up about this or how to config RTX4060 or when available?

yes if i am not wrong and it is called FLEX mode

if i am not wrong, 12gb + 8gb
8gb +8gb will run in dual channel and remaining 4gb will run in single mode. you can google more about this 👍🏻
