Patrick, OT <fill rate> The fill rate is a strong function of rendering parameters, but mostly it is the size of triangles. What I am trying to say that it is meaningless to say "fill constrained" without specifying the typical triangle size. If you check out performance results for i740, foil 12: eecs.umich.edu you will find out that the boundary between "fill-constrained" and "CPU-constrained" is in the range of 50 pixels per triangle. If your benchmark is a rotating doughnut made of 300 triangles of 100 pixels each, it will be "fill-constrained" with almost any processor. If your 3-D object is a detailed gargoyle, with 3000+ tiny triangles in tessellation, you will be most likely constrained by CPU/system set-up rate. BTW, the i740 does not look any better than average 3-D card...
