Used 540 in both 8 . 1 and 10 . Alright for basic use , albeit performance is a bit slow . Go for 640 if it is possible . Would recommend 540 over 550 though . <| sep |> Bantz aside , and as you pointed out , that ' s a pipeline problem . If you think that we are determined by our environment , then it is odd to blame individuals for systemic issues on which they have no control over . Besides , I am genuinely curious on what you would find an acceptable setting to ask someone out . In my home country , there is hardly anyone supporting that thesis men shouldn ' t engage with women in the streets . It could be a latin v . anglo culture thing , but anyway , the ones who do are generally higher middle class . A couple people have argued that it is for classist reasons . I am not saying you are obviously , that ' s just a little morning anecdote .
