if i were gonna get a setup like this, i dont think i would even bother with the card, considering its price/performance ratio. you can get 3 5870s for $1200 and get better performance, then if you want to overclock (like you no doubt would with the 5870x2 ARES), you drop on full cover blocks and water cool them. in the end you would either get significantly faster performance for the same price, or insanely faster performance for only a few hundred more. these cards definitely win the "more money than brains" award. the only way a card like this would make sense is if they tweaked the shit out of the board to allow for the types of 1GHz overclocks we see people getting on single 5870s, only on both GPUs, but even then you could get 2 5870s or 1 5970, and a water loop to cool em, for the same price if not less
ed: they need to do a comparison using a 2gb 5870 + ARES as well. if it shows a significant boost at the extreme graphics settings you would use with this setup over using a 1gb 5870 + ARES or a 5870 3x CF setup then it would be worth noting. it would of course also have an effect on pricing and my argument comparison points, since the 2gb 5870s start $100 more expensive than 1GB models
