### ⭐⭐⭐⭐⭐ AAA+
*by J***N on 16 February 2020*

Works perfectly. Good buy. Arrived in brand new Condition.

### ⭐⭐⭐⭐⭐ Sin problemas
*by W***Y on 9 March 2019*

de momento bien, aun no puedo calificar para juegos debido que aún no tengo una buena pantalla asi que no puedo ver bien las resoluciones que me ofrece el solo procesador. Pero por fin tengo lo que queria, el producto que elegí para mi pc, fui exigente con el empaque, tengo muchas fotos, llego con su sello de intel, algo que me dio tranquilidad, llego limpio y sin huellas digitales. Las temperaturas me han parecido bien, tengo una refrigeración liquida, no veo problemas, en inactividad esta en 29 grados. Ya mas adelante hare una actualización y de verdad no creo que tenga problemas.
