if you don't plan on overclocking, you can settle for any 965, 975, or 680i board you want. All you have to do is find one that has 2 ide ports (i'm assuming you have at least one cd/dvd drive to connect as well as the hard drives). If you don't have any cd/dvd drives to connect, then you only need one ide port. All of those boards will support your memory, but unless you overclock, it is not going to be running at 1066mhz (i might be mistaken, I'm basing this off the C2D's speed at stock which does not even run 800mhz ram at it's rated speed).
