Yea I read those reviews pretty much the day they came out. And pretty much all of them show that the card is no faster than a pair of regular 7900GT's in SLI, and in some cases slower than a single 7900GTX.
So "no problem" with AH is not really the question you want answered... Yea it'll probably run but since you're probably the only person who's ever seriously considered getting one and playing AH with it, you're pretty much the crash test dummy on this experiment
I think the only way to really find out is to either buy a rig for yourself, or buy an SLI rig for HT and bribe him with scotch until he agrees to spend a week writing a few SLI optimizations.
The con would be a good place to make your case, but I wouldn't place any bets on the outcome
edit - regarding why you specifically asked skuzzy, if you browse back through this forum you'll find that (at least to the limit of my memory) HTC has almost never intentionally made recommendations about hardware purchases for the game. The closest they have come in the last few years is when the latest graphics engine initially worked a LOT better on nvidia cards than on ATI cards, and skuzzy favors intel cpus in general over AMD cpus. I think the performance on various video cards has evened out a bit but I also recollect that they caught a bit of hate over the simple admission that they hadn't gotten AH to run on ATI cards as well as Nvidia cards.
Couple that with the general grumpiness from when the original CK beta had S3 card specific optimizations, and like I said above you might have to corner HT or pyro with a few liquid bribes to get them to speak off the record on the subject of game rig hardware choices.
Plus they coad on rigs many of us would consider hopelessly antiquated, so it's possible they've never even seen their game run on the latest hardware. Seeing the crickets chirping from the lack of response from skuzzy, some of us have tried to fill in the blanks. Sorry if that upsets you.
