with crossfire you can take any X850 and another X850 that is CrossFire edition
and the crossover
AND THE SPECIAL MOTHERBOARD (this is KEY)
aside the fact
while dual X850XT PE's would provide a ton of powre
consider
A) nVidia and ATi release new GPU's by July
B) It still doesn't support SM 3.0, meaning 6800's can defeat it at that
i was wondering if u need a crossfire card and a regular x800 or x850 series card or can u just use a crossfire card and nothing else?cuz for nvidia u can use one card and later upgrade to sli
