I don't get a problem but I have a different graphics card.

But increasing the PlotPoints to 100 is the brute force method. It is slow 
and rotating the image with the mouse is very slow. It is much better to 
keep the PlotPoints relatively low and use MaxRecursion instead. Compare the 
two following plots.

Plot3D[Sin[5 (x + y)], {x, 0, 2 Pi}, {y, 0, 2 Pi},
 Mesh -> All,
 MaxRecursion -> Automatic,
 ImageSize -> 800]

Plot3D[Sin[5 (x + y)], {x, 0, 2 Pi}, {y, 0, 2 Pi},
 Mesh -> All,
 MaxRecursion -> 3,
 ImageSize -> 800]
