This sounds like it COULD be great news. But will all 680X0 run? Will there be a patcher that catches ALL unsupported opcodes? If so then it will be great... if not and it only speeds OS friendly stuff then not so great.
The AGP/PCI support is also very useful but perhaps the comments on cost ARE valid. Take €349, add on VAT and delivery and convert to Pounds and it is over £300. That is significant dough!!!
