AFAIK, the new 7447A will be cooler (but also more expensive(?), especially at higher speeds?) and based on what has been said earlier (about cool/fanless computing) as well as those reasons (heat, (extreme?) costs), my guess is that the focus will be to build a silent, fan-less CPU card at a price that customer's are prepared to pay. I would be surprised if the new G4 CPU card will come in speeds faster than 1GHz, but perhaps they could *also* make a small, limited production run, with fan, based on the fastest G4's available, to both test the market for it and also to claim the crown of being the fastest non-Apple PPC machine available?

What would *you* be prepared to pay for a top speed G4 card (the card+CPU/cooling alone, excluding motherboard)?

I myself would be prepared to pay around 500 EUR for a 1.4-1.5 GHz G4 card (and I would expect that to have some kind of fan as well). That is *my* limit, and the question is if this price would be possible to achieve?
