I have the same problem.
The problem appears between 57 and 58 plotpoints.

Plot3D[Sin[5 (x + y)], {x, 0, 2 Pi}, {y, 0, 2 Pi}, Mesh -> None,
 PlotPoints -> 57]

is fine, but

Plot3D[Sin[5 (x + y)], {x, 0, 2 Pi}, {y, 0, 2 Pi}, Mesh -> None,
 PlotPoints -> 58]

shows already a degraded picture.
I have a Nvidia GeForce  8400 GS like yours (without the M though).

Is this a general problem with Nvidia cards?
