Why is it that when I replace a GTX 660ti card with a GTX 560ti card that the Luxmark score(default Sala test) goes up from 682 to 1162? Wouldn't you expect that the older 560ti card to have an inferior Luxmark performance? The 560ti has 448 cores and the 660ti has 1344 cores... In all other tests(Geekbench, Novabench, Cinebench OpenGL) the scores are virtually the same. All this with a Z77X-UD5H + i7-3770K and Mountain Lion 10.8.4.
