on Intel Chipsets, better go for Asus, if you would have been building AMD system on nVidia chipset then I would have definately recommended MSI for their better performance with nVidia chipsets boards, but in intel chipsets, Asus is surely a brand. check out prices for P5W-DH on 975 chipset. spend some more money, and you wont regret it. also Asus comes with Passive Northbridge cooling, where as MSI is coming with Active (noisy)
