well in fact i havent dicided what MB i would buy.. the first MB i wanted to buy was Tyan Tempest i5400PW... but i couldnt buy it, here in mexico nobody sell that branch..
i forgot to tell you that i already have a pair of E5410 xeon`s CPU, so i have 2 options a Intel S5000XVN or Supermicro X7DWA-N, .. but i dont know what's better of those MB... i think Supermicro MB is better because it's chipset 5400.. all people buy intel MB.. so what's better to you ?
