I am in the market for a new computer. I plan to probally use only one video card at a time (Nvidia cards). I was still thinking of an Asus A8N SLI premium 939pin, even though I don't plan to use SLI, because the board looks good. I want this comp to last a while, so I am getting the "new" PCIe interface and an AMD 64 so I can upgrade to Windows 64 bit when it becomes popular. However, AMD does not support DDR2 memory. Do you think it is worth getting the Intel LGA 775 socket since it seems the 939 socket will be outdated soon, but intel does not support 64bit Windows. Which is more important for the lifespan of the computer, DDR2 or support for windows 64bit + AMD future support for dual core 939 pin? Thanks
