The reason I went with my Gigabyte board is for three reasons. I'll list those, but please keep something in mind first: I am an avid fan of Asus boards (my last 3 have been Asus).
1) Availability. The Asus boards I want are not available in the US right now; only the Asias and possibly Europe. NewEgg has some models which aren't even listed on Asus' site, which makes me wary.
2) BIOS options. Gigabyte, despite all of the reviews, has the most configurable options there is. Asus has been gradually cutting back their BIOS options more and more (for no reason). Intel boards have never come with very many options.
3) Support. I have dealt with Gigabyte in the past, speaking with both managers and techs at their California facility via phone, in attempt to diagnose some issues with older boards (which they fixed!). Talking to Asus is like pulling teeth -- you'll be lucky if you can get a response from them via Email, and whoever you talk to on the phone is always either A) complete generic tech ("did you try reseating your RAM?") or B) a secretary who simply acts as a communication liason, forwarding requests blindly to others.
I **did not** buy my Gigabyte board for overclocking. I do not overclock, nor will I ever.
I will state that the Conroe-based Gigabyte boards seem to be very picky about memory; no denying that. But I always review forums before I go buying a board -- and because of this, I went with purchasing Corsair Micro memory purely because I didn't want to take any chances.
Hope this helps answer some of your questions.
