i just want to know what do you think about the Intel Motherboards in general, some experiences and opinions
Do you mean the motherboards that are actually manufactured by Intel, or those with Intel chipsets?
Assuming you mean Intel chipsets, I've had an Asrock Z77 Extreme3 for over a year and a half now and it's handled my i5 3570k OC'd 24/7 extremely well.
i mean the manufactured by Intel XD
Aesthetically some of the boards are rather dull, but feature and performance wise I would chose an Intel board over several other manufactures especially for workstation/server level gear.
