Actually it more than likely does mean a new mobo. The core logic in the chipsets can only support so much through the BIOS. 915 and 925 boards although LGA775 don't supoprt dual cores.It's very nice that it's Socket 775, I think that will be a huge plus for current Intel users with that socket. This means they dont need a new mobo, just pop in the new CPU and your good to go. With AM2 on the other hand, you need a new mobo.
This was a misleading statement, as apj101 mentioned, there isn't anything anything interesting on the AMD roadmap yet. That said AMD will be looking to start a new design, they can't ride K8 for too much longer.me said:Keep in mind AMD will probably come out with a new core design soon after the AM2 launch to compete with conroe.
Again to those of you who think it's an unfair comparision (conroe vs a current A64), it is and it isn't. It is in the sense that it's new technology compared to old, it isn't because AM2 only adds DDR2. DDR2 only brings bandwidth to the table, AMD operates on low latency (hence the integrated memory controller). DDR2 800 has enough bandwidth to hide high latencies but then I suspect performance will be about the same as AMD currently gets with DDR400.
