Look at quake 3/serious sam for opengl fps. As for it's poly count, I don't think it has been released yet, what they say the card can do is pretty useless because it is the theoretical poly count which is never achieved. Basicall the kyroII is killer at low res and even more so in high res.
In games that require a lot of bandwidth (games involving high textures) the Kyro II actually outperforms the GeForce 2 Ultra. Other than that it's a mediocre performing card. It performs EXTREMELY well in Serious Sam- other games it peforms about the same as a GTS or MX.
