De flesta tillverkare sparar de lyxigare GeForce 80-klassade grafikkorten till sina flaggskeppsmodeller för entusiaster. Legion Y900-familjen brukade tillhöra den kategorin, men Lenovo har satt den serien i vänteläge vilket gör Legion Y700-serien till deras mest avancerade alternativ. Resultatet är en mittenskiktsenhet med en toppskikts-GPU till ett betydligt lägre pris än konkurrerande "super-modeller" som Alienware m17, Asus ROG G703, MSI GT75 eller Acer Triton 700. Denna Lenovo-laptop har samma spelprestanda som entusiast-alternativen men kostar tusentals kronor mindre, i huvudsak på grund av att den har en enklare och mindre eccentrisk design på sitt chassi.
CPU-prestandan är högre än genomsnittet för Core i7-8750H på grund av utmärkt förmåga att upprätthålla Turbo Boost. Både kärntemperaturerna och ljudnivån är lägre än förväntat med tanke på den tunna formfaktorn och den höga prestandan.
Eftersom Legion Y740 har ett mittenskiktschassi är dock det första intrycket inte lika starkt som hos tidigare nämnda toppskiktsalternativ. Lenovo-modellen är mer benägen att böja sig eller gunga än de robustare (och dyrare) modellerna MSI GT75 eller Asus ROG G703. Vår specifika enhet led också av måttlig till kraftig bleeding och oprecisa färger. Tangentbordets knappar är dessutom mjukare och generellt sett sämre för spel. Gamers kommer inte sakna prestanda, men sämre chassi och knappar kommer ändå begränsa den totala spelupplevelsen.
Mittenskiktsmodellen Legion Y740 säljs för mycket mindre än konkurrerande entusiastmodeller på 17.3 tum samtidigt som den har samma avancerade CPU och GPU. Den är riktigt prisvärd när det kommer till prestanda så länge du inte har några problem med dess anspråkslösa design och ett chassi som böjer sig.
