how is the x1600 so much slower than the 7600GT, hardware wise there almost identical but i would expect the ATI to be faster cause of that fancy 256-bit ringbus business, they both have 12 pixel processors, 5 vertex processor and 8 ROPs i believe, both have 128-bit memory interface with high memory clock speed (x1600 has 256-bit ringbus thing) and hell the x1600xt is core clock is higher, is the x1600xt really a bad card or is it stricty a software problem, ie. the hardware available not being used efficiently like the drivers?
