AMD has done the same with theirs. You complain about Intel's slot 1. How about AMD's slot A? Upgrading to socket A required a new motherboard. You complain about changing bus speeds. How about AMD going from 200MHz to 266MHz? Upgrading the CPU here required a new motherboard. You complain about Intel moving from SDRAM to DDR. AMD had to make the same transition, and that required a new motherboard. Finally, you complain about Tualatin incompatibilities with the older socket-370, but AMD is having incompatibilities with Athlon XP on older motherboards. See this:amdmb.com "Note: if you have a board without the proper bios – the motherboard will NOT post in most cases. You will have to use a standard Thunderbird or Spitfire chip to flash the bios to the version with the Morgan/Palomino support. This may become a hassle if you are buying your system components new and do not have a spare processor or cannot borrow one." Next year Intel is upgrading to a 533MHz front side bus, and that will require a new motherboard (unless you plan to overclock). If AMD wants to keep up with performance, they will need to launch 333MHz EV6 bus Athlons, and that will require a new motherboard. So I don't see what your problem is. AMD has had the same kinds of transitions as Intel. Intel of course had to transition Pentium 4 from socket-423 to socket-478, but that's the only difference I see. All your other examples match transitions that AMD has made as well. wbmw
