The speed of your program would mostly depends on what features you want to support and what data structures you decide to incrementally maintain in the lowest level. Back in 2010, in Erica I got only about 5000-6000 pure random playouts per second on 19x19 at one 2.26 GHz core. For me what really important was the speed of the heavy playouts but of course the light playouts shouldn't be too slow anyway.
To learn the tricks (such as using pseudo liberty) for making your program fast, check out Lukasz Lew's libego.
