I think that I should suggest to you these 2 boards
Asus A8N SLI DLX or (premium as the DLX ones chipset fan is very I had to change it within one month but the premiums heat pipe scores over anything else )altough its true that asus doesnt have asynchrous timing for ram and fsb but the memory ratio changer in the premium version makes up for it.

Or go in for Epox EP-9NPA+SLi It has asynchrous timing for ram and fsb and every feautre except 4 sata ports of asus it has 2 of silicon image.http://www.epox.com.tw/eng/products_content.php?ps=346
