I ended up getting an Asus Zephyrus G15 with a Ryzen 9, 32GB Ram and a 3080 mobile. It's been just fine for getting baseline numbers and being able to run most things for debugging purposes. You wouldn't want to run long training sessions on any laptop as the other comments say, but when I bought mine it was ~$2k. It's absolutely not worth spending more than that for a machine that is going to be limited to approximately the same performance that lower-priced laptops will have because of thermals. Don't buy the $5k system (or frankly the $3k system either). Way overpriced and the extra $ won't buy you any performance or productivity over much cheaper systems. It's all flash and marketing.
