Im currently looking at buying a mobo that will work best with a 6-core i7 processor. I have nearly made up my mind with the Asus P6X58D Premium board, but a lot of folks have been telling me great things about Gigabyte. This is my first build so i dont have experience with either company. I will OC and will use RAID eventually, and crossfire or SLI too.
I used to like ASUS, but they got much worse lately, especially their support. I tried to update the BIOS on my "M2N-SLI Deluxe" and the board is a brick now. ASUS Flash utility is broken, BIOSes that ASUS put on their website are often for the wrong boards, just take a look at ASUS forum - many people with the bricked boards.
Based on customer satisfaction, it looks like Gigabyte is the best.
Gigabyte is relatively cheaper than asus i think. u can get all of u get from an asus board with gigabyte and save money that u can spend later for upgrading (of course if u plan to upgrade your pc next days...). maybe u should take a look at Gigabyte GA-X58A-UD3R. It's much cheaper than P6X58D Premium at newegg..
