Hexus.net have taken a look at the Visiontek Xtasy GeForce4 Ti4400. Here's a snip:

    "Performance from the Visiontek is stellar, there is no question about it. Infact, I hinder performance running with the XP1500 since the card sits and waits for data from it for the most part. You really need a good CPU to make the most of these cards but on the flip side, that can be a good thing...

    ...the advanced rendering logic on the NV25 GPU make for some serious performance. Dual vertex shaders, upgraded pixel shader, new 4 split memory crossbar along with Accuview antialiasing with the new 4XS option and nView make for a very nice graphics card."
