[phigdon]

what makes the 9800 GX2 nVidia card worth $150 more than the ATI 3870 x2?

Nothing really, its a little faster. I also don't like the cooler, it dischages all its heat into the case rather than out the back like the 3870 X2.

well I believe its application purposes and the nVidia brand name mostly that drives the price.

nVidia
3D API
DirectX 10
OpenGL 2.1

ATI
3D API
DirectX 10.1
OpenGL 2.0

OpenGL is used for making 3D stuff I know that, and DirectX is more used for running 3D. So Game wise I could see ATI being better, but for professional business I could see them going for nVidia. O and nVidia has lifetime warrenty while ATI has 3 years (I couldn't see needing longer then 3 though).
