With Fermi and newer (i.e., Kepler) hardware, there's not as much to be gained by using texture memory. On previous hardware, the texture cache helped to speed up some kernels that had non-uniform memory access patterns; the Fermi/Kepler hardware has a larger on-chip L1/L2 cache which serves the same purpose and does so without requiring the programmer to write extra code for working with textures.
