Intel's lowest dual core chip, the 820 will retail for around $240, not $400. The 840, aka non extreme edition with about 5-10% less performance will retail for $500.
ok well the A64 3000 is still ~$140 and the $240 is the price each if you buy 1000 so it will end up being a lil higher. and when amd release it's dual core chips I'm sure the pricing will still be better thats whats make them so good comparable performance for a cheaper price, one cpu beating the other by a few sec's doesn't mean much if you have to pay twice the price
