Theres drawbacks by going with x2 cards. If you dont achieve a certain framerate you may experience microstuttering. The GX2 does great in most games, and youll hardly experience it in the majority of games out now, tho that could change with more demanding games of tomorrow. I would imagine that future games will be optimized for dual card setups, or x2, but will they slow slower x2 cards down where microstuttering becomes an issue? Ive read a few people whove bought the GX2 who later returned them, because a certain game they liked microstuttered and it drove them crazy trying to play it. Not alot has been said about it, and youd have to really search around the web to find a certain scenario regarding this issue WITH a certain and game and certain card. It doesnt happen alot, but when it does, say your favorite game, it sucks
