Best praise vs top criticism for Lenovo Legion Slim 5
βThe Lenovo Legion Slim 5 is better. The 4060 is a much better choice than the 4050 for gaming. The CPU on the Acer is faster but the GPU is bottlenecking it too much. Also the 7640hs on the Slim is one of AMD's newer Zen 4 CPUs which is more than enough for games, whilst also being better on battery. At $899.99 the Legion Slim 5 is a really good deal. Build quality and thermals should be good on both laptops. Screens should be similar, no significant differences. Battery on the Slim is better. I think both are upgradable in RAM and SSD but you should double-check if that's a concern for you.β
βIt's a 4 year old IdeaPad, not worth upgrading now, I'm looking for a gaming laptop now, like the Lenovo legion slim 5, I want a simple looking gaming laptopβ
