1. It doesnt have Pixel Shadel 3.0yes the card has PS3.0 but no games currently even take advantage of this so going with the x800 is certainly not a bad choice
2. I initially though the same. Play FarCry 1.2 -- there is a difference and a DAMN noticeable one at that
And in the case of the X600 and X300 ... dissapointing cards .. extremely so.as not always newer is better, like in case of Intel Prescott.
