I should purchased a Asus. Never had problems with them as they have always been top notch.
If you create a new computer, especially from a new Mobo, you will definitely want to reformat and reinstall win7.
1366 is the newer architecture. If you want the best and for the i7, go with a 1366. These mobos usually have like 3 PCIx slots, hold like 24gig+ of ram etc. More pricey though.
i5 is cheaper but still nice and you can still get a i7 with a cheaper 1156 mobo.
