That has actually not been true for a few years by now. nVidia has long taken the lead in IQ thanks to a much better implementation of AF and slightly better AA modes. The argument that ATI may be a tad bit slower but offers better IQ is obsolete and has been for a long time already (like when the ATI 9800s were around). You may want to update yourself on this stuff some time.
