It loses a degree of smoothness from the original, but it is still
a vector image, not a bitmap image.  It will scale to any size
without pixelating; in most cases you will only see the jagginess of
curves if you zoom in very far.  There is an option for 'pstoedit'
that lets you increase the smoothness of its output (by using
shorter line segments).  Specify something like “-flat 0.01” to
improve output smoothness.

You can also load a DXF file directly into Inkscape as
well instead of using QCAD.  Then the process goes like:

DXF ---(Inkscape)---> EPS ---(pstoedit)---> PCB

Inkscape doesn't have as advanced a DXF processor, so some things
aren't rendered true to the original, like font styles, etc., but
it has worked well for importing complex board outlines, etc.
