Verdict
NVIDIA GeForce GTX 1070 SLI Mobile
3.5 / 10 Expert Rating
A fascinating but obsolete dual-GPU experiment; SLI's driver dependency means a single modern mobile GPU is the far more reliable and often faster choice today.
NVIDIA GeForce RTX 4080
8 / 10 Expert Rating
A solid high-end pick if its price and 16GB VRAM allocation match your target resolution.
