The guys over @ Overclockers.co.nz have posted their review of Triplex's Millennium Silver GeForce 4 Ti4600! Now if I wasn't waiting for the Geforce Fx this would be the Nvidia graphics card I would choice! Here's a snip.

The highest working speed is 320Core/760Memory. I was not able to push the speed any higher without random lock ups. This is pretty average among the Ti-4600 cards with similar specifications.
