I have asked at subsim some time ago, now there at SBP boards, and several people in real life as well. I still cannot beolieve how many very different, even contradicting answers I have gotten. But if it is how ssnake says, it should be taken into account: there is little reason then to buy a quad if you do not plan to get software optimised for that. Probably better to got for a duo - but that with as many GHz as your budget allows.
