Per ati, m x1950 needs a x1950 to run in crossfiire mode.
I have the little dongle.. do both cards need a power connected in the back of card or can one draw from the board? OR do both cards need a rear end connector?

I have 600 watts with t480 w dedicated to the 12volt rail... I am not sure this will be enough..
thoughts?

600 watts should be plenty for your rig. i'm on 620, and i have a quad.
both cards need to be powered by the psu, so yes, plug them both in. also, you need two crossfire bridges.

A> two crossover thingies?
why not only one, confused?

B>I am now looking for a card, should the mem size match? speed?
IE my HIS comes factory overclocked?

great, almost got one with 512 and mine has 256, am I wasting time and money, or does the sli RULE two card configs? I have a p35 crossfire board and a card, and with cards falling in price I thought I could easily upgrade... or I could trade board, brand new, for 680i chipset sli board and go the dual 8800gt's... that would be sweet!



Seriously though, how does sli and xfire compair with like cards?
