I have the msi x1900xtx w/512 and might get a radeon x700 w/256mb

Would I notice much difference running both cards?
 
you can't run crossfire with 2 different ati cards. Why would you even want crossfire? You have an x1900xtx.
 
i thought you could crossfire 2 different cards and combind the speeds
 
From what I recall you should be able to run those in crossfire however the 1900 would downclock and downpipe to the x700 so you would be running an effective dual x700
Enjoy if that's your cup of tea.
 
If anything to save money you crossfire a X1900XT.

Maybe when a cheaper version of the x1900 comes out (X1900 GTO?) that would even be a better choice.
 
crossfire is only worth it using high-end cars - otherwise you'd see better performance on a beter single card. I bought a 2nd x850 fo cf, but soon returned it and took out the 1st one for a x1900, giving better performance than the 2 x850s, and shortly after that bought a 2nd x1900. still just short of 10k in 3dm06 though...

No, that won't even happen.

With every dual-video card solution, the cards have to match or at the very least have very similar architecture. You can crossfire any combination of X800, X850, X1300, X1600, X1800 and X1900 cards but not between each other - ie., you can crossfire an X1800 Crossfire Edition with an X1800XL but you can't crossfire an X1800 Crossfire Edition with an X1300.

What will happen with both in the computer? It'll boot, but the X700 won't do a thing - you'll go into the control center and find crossfire mysteriously grayed out - not that mysterious though considering it has a big label explaining all of this on the boxes for all modern ATI cards...
