Thanks John,but I decided to go back to Abit boards, and will get the KN8. Of course, needing a new video card, I'll get an ATI X800. Now, to get a Xena HS...

Keith - I think even Adobe are recommending the NVidia QuadroFX cards. The X800 is a stellar performer in the gaming arena where you can overclock, but I can't help feeling the manufacturers are trying to tunnel you down a certain path to make their support job easier - and perhaps your life easier.Avid also recommend FX3000 minimum these days.

I don't know but I think it's the OpenGL implementation that they are using that perform a lot of the real time effects that are built into these systems. Boris Blue also has a very narrow range of Quadro cards. Having said the X800 may work perfectly well for you, just thought I'd give you a heads up.

Thanks for that heads up. I decided on the ATI for two reasons- I have always found ATI to be reliable, and the price wasn't bad... and the place has them in stock. Ok, three reasons ;)
