Just got word from Thomas that he's posted his GeForce 4 Ti 4600 Review! Here's what he's saying.

Our NVIDIA GeForce 4 i 4600 review is online. It covers topics like:

GPU efficiency (NV25 275/275 vs. R200 275/275)
Do I need 128 MB ?
FSAA and aniso. filtering quality and performance.
OpenGL and DirectX benchmarks.
