DDR3 boards by 2007!! Buying a PC based on these chipsets is going to cost a bomb. Why can't they make DIMM sockets that are compatible to both DDR2 and DDR3? or even DDR4 when it comes out. Say for eg, you can insert a 184 pin DDR modules in a 240 pin DDR2 socket. The rest of the socket will remain unused.
At this rate there will be nothing called a future proof PC. Infact such a time has already arrived. So its useless to buy a PC with a motherboard that supports a "future processor", because by the time you decide to change your proc your mobo will be already outdated. If you are buying a dual core CPU, don't buy a mobo that supports quad-core CPU. It wil be just a waste of money. Don't look for features in a mobo that you are not going to use, just because its going to look "future proof".
