I have never really heard about the cpu board?
If it was me, I would just focus on the ability to upgrade with the hardware that will work for the moment. If you currently have a 939 cpu and are happy with the AGP, then there is no need to look any further.
Your PC is already new enough, and the should ram is sufficient enough to handle most of today's needs.
If you plan to upgrade to the AM2 in the future I would recommend replacing the mobo, and ram at that time. Keep in mind that AGP may not be available at the time and you may be in need of a new graphics card as well.
Hi, I'm in need of a computer upgrade and I need to buy a new Motherboard as my current one is Socket A with AGP, so I want to get an Asrock 939Dual-SATA2 motherboard. This Mobo supports socket 939, PCI-E, and AGP so it suits my needs.
Anyway, the Motherboard can later have a cpu board put in it (the first time I heard of such a board) to accomodate socket AM2, which allows me to use DDR2 RAM to get better performance (to my knowledge). Will the Mobo support DDR2 RAM? More importantly for me in the future, does DDR2 RAM need a specific port (if that's the right word) or does it depend on the CPU?
