I'm looking to switch from mac and get a powerhouse laptop that will last me 5 years and be great for gaming. I have only seen reviews for the 300hz non-4k one, are there any around for the 4k version" For anyone that has it or plans on getting it, why/is it worth it? Also, am I forced to get a 4090 (not 4080) with the 4k? The ROG Zephyrus is $3500 for the 4090, so I was curious about getting that.
