my only question is, if they are in fact crippled 570's, how is it that they have no issues with overclocking? the power phase setup on the 570's caused issues for overclockers..how is that not affecting the 560 448's then?
The standard 560 and 560 Ti's use the nVidia GF114 core with the full 384 shaders.
The Ti-448 is based on the 512 shader GF110 core that the 570 uses. I suspect that is a better overclocker because of a newer design.
