I dont see them as the same so I wouldnt call it a rebranded 460. The 460 has the GF110 chip and the 560Ti uses the GF114 chip not to mention more mem bandwidth as well as more cuda cores.
Very true, the 560 has the same shaders as the 460 (336) but is clocked higher. The Ti has 384 shaders & is clocked roughly the same as a vanilla 560 in stock form.
