yeah you're right, though i think the main reason why they're bringing out the bad axe 2 is because of kentsfield. Though would it say on the box that you're getting a BX2 instead of a BX1, as they're both of the same chipset, the 975x?
1)someone said that there is a rumour that md quad core (native) will be on socket F NOT AM2, not sure about it though, if it is true or not.
2) Native intel quad core will be released in 2008 with the Nahlem uarch (is that the right uarch)? only two years away, can't wait! LOL
3)No, don't wait for 4x4, it's 'rubbish,' expensive, power hungry (compared to kentsfield) and not to mention expensive. You can't use just one cpu and then buy annother when you need more horsepower, you have to BUY BOTH at the SAME TIME. All it is is just a server platform with ddr2 and other desktop like attributes (sli etc)
kentsifeld, if it's the same performance or better than 4x4 will (i guess) use less power because there is only one cpu core. 8)
athlon fx62 (just for the sake of comparisons, i know they use fx 70 series in the 4x4 platform but i dont have the data)= 125w tdp
now to operate the 4x4 platform you need 2 cpus so double the power of one fx62 and you get 250w, JUST FOR THE PROCESSOR(S)....
And this 4x4 might not even be able to beat kensfield....
