Verdict
ASUS ROG XG Mobile
8.5 / 10 Expert Rating
Exceptional performance and portability for its narrow compatibility list, but the closed ecosystem and steep price limit it to committed ROG Flow owners.
GIGABYTE RX 580 Gaming Box
6 / 10 Expert Rating
A dated but genuinely plug-and-play option for 1080p eGPU gaming, now most sensible as a budget used-market pickup rather than a current recommendation.
