nope, you need a mastercard.. with CrossfireJack's mod, you can enable 2 1900GT's, but it isnt as high performance as a normal card, and a mastercard.

what is the crossfirejack's mod
500w fsp bluestorm
msi 965 neo it was cheap
intel 805 overclocked to 3.2
1800xt 250meg
ocz 1024meg ddr2 800

its just a driver hack iirc.. enables limited crossfire on 1900gt's

i'd just go with a mastercard..

i heard the crossfirejack's mod doesnt even work with x1800xt's and even if it did the performance probly wouldnt be as good, deffinetly go with the master card

its still waaay in beta stages, so its nowhere near finished yet. I have a feeling it will work very well, and will be popular, once he adds more support for cards.

actually, crossfirejack seems only to force the "crossfire" box to be checked, I'm running X1900GT Crossfire without crossfirejack with cat. 6.8

[W2hCYK]

well thats smart also, haha..

you using dual gt's? no mastercard?

[Changis]

nope no mastercard.
why would i want a master card that will be downclocked, stripped of 4 pipelines and half it's ram? :P I'ts not officially supported yet, but I have tipped the cat. crew that they should let us choose wich rendering mode we want to use, or atleast force AFR without Cat. AI @ advanced...

Yep, you need the highly expensive X1800 CrossFire card (Master Card) aswell as your X1800XT :(
