I was planning to upgrade a new motherboard as I want to upgrade a lot of hardware like graphic card , hard drive that would need a new slot (PCI-Express ,Sata ,DDR 2).The problem is I have three DDR Memory which amount 1 GB MB RAM, I wish to know that is that worth to change a mobo with DDR2memory slot ? As I knew that many computer user around are still using the DDR Memory , I have to be careful for this decision to save the cost but worried too if the DDR memory would outdate soon.
