I would never waste my time with any of these mentioned.
Because I'm getting a Razer Blade 18!
To anyone on the lookout for a new performance laptop, here is a tip.
For 20 years now, I stick with Razer, Asus, MSI and Lenovo for one big reason.
When a model of those companies laptops is superseded by a new one,
they eventually release new GPU Bios files to boost performance a bit.
My last 3 laptops were Asus Rog Strix. Bios file came out that boosted the 1070 from 115 watts to 130 watts.
MSI GT76 Titan boosted the RTX 2080 10 watts to 210. (Just 5 watts less than a desktop 2080)
My current laptop, a Lenovo Legion 7 boosted the 3080 from 115-150-160 to adding another 15 watts to the top settings for 115-165-175.
Remember to check their websites. The updates DON'T
happen automatically and for some reason they don't keep them up forever. (If anyone has a theory why, please share).
