Default Should i still buy the nexus 7 2013?

Hi guys,

The title says it all! I currently have a Asus tf300t and it's absolutely terrible! The tegra 3 in it is extremely slow, I just hate it! I thought about buying the nexus 7(2013) is it still a good device or should I wait for the nexus 8?( rumours state that it will have a Intel CPU and a powervr GPU which doesn't really like) also I know that they will stop selling the nexus 7 sooner or later but I don't know when, anyone have an estimation? ( probably when nexus 8 releases)

Thanks,

Noahvt
