I don't have experience of using dual gc before, either crossfire or sli
but I've been googled for so many times in regarding of this
I can tell you, out of all the search results, all of them recommend don't do it, better spend the money on buying a single and better card.
reason is
1. dual card driver support is.. erm.. how do i say it... "slow"? in another word, not good driver support.
2. your game need to be optimized/developed to be able to utilize crossfire/sli
3. very high power consumption (which do not justify the level of performance upgraded), you need a powerful psu also, which mean you need to spend more budget into psu.
they say,
only crossfire/sli if you happen to get a spare card on your hand somehow and you do not want to spend money to upgrade your system.
else if you are buying new gc, don't do this, spend it on buying a better single graphic card.
again, I don't have experience of crossfire/sli, what I said above might be correct or might be wrong since I learn them from google search. dear sifus and masters here, please correct me if I said something wrong, cheers~
