Hi guys, currently looking for android box due to skybox no longer able to use.

Quick quiestion. Is ram capacity affect the performance much?
Got an offer zidoo 1gb ram (with kit kat) + 1 month subscription for rm250, Z1 2gb ram (with lollipop) for rm359, and Z1 plus 2gb ram (with marshmallow) for rm399.

If there is not much difference in performance I just buy the 1gb ram zidoo. Thanks btw.
