Depend on you need, for gaming only. I think you better go for steam deck oled. Big battery, efficient processor, and oled benefit + hdr
If you want to somehow use it as laptop replacement, go to lenovo legion go. Big screen really help.when you use as workstation. But yeah, windows suck on handheld.
Personally i will go to steam deck, as current apu (even the z1 extreme) dont have enough power to run AAA game with high setting comfortably. And you also save money while doing it (if I’m not wrong 1tb deck oled still cheaper than other handheld, atleast in my country)
Final fantasy xv, on 3.4 stable it will dip below 30 and have frame stutter
In 3.5 at 800p, i can get stable 40 on roaming and never below 30 while fighting (tested on chapter 9)
