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 2080 Super
5.5 / 10 Expert Rating
A solid 1440p card in 2019, now a budget used option outpaced by two full architecture generations; fine cheap, not worth paying a premium for.
