I understand you wanting the ASUS A7N, make sure it has the RAID option and the much talked about on board sound, don`t forget that (according to Tom) there are some 32 variants of the chipset.
I myself am still running the A7V133 and awaiting the new nVIDIA chipset boards, however, I will wait untill Tom does a round up of all the partners before deciding on the M/B I will use.
