So you traded cpu performance for gfx performance. Great >design. you are not making any sense. first, "I" did not do anything. second, it's application performance that matters and if PhotoShop runs faster with a 50MHz l2-cache-less module than with a 50MHz l2-cache-full module then where is the problem? all that matters to most to us is that the application goes faster.
