Given the function $f(x)=\ln x- \frac {1}{4}x+ \frac {3}{4x}-1$.  
(I) Find the intervals of monotonicity for the function $f(x)$.  
(II) Let $g(x)=-x^{2}+2bx-4$, if for any $x_{1}\in(0,2)$, $x_{2}\in[1,2]$, the inequality $f(x_{1})\geqslant g(x_{2})$ always holds, find the range of the real number $b$.
