i guess now back to you, what spec that you need. like how many ram slot, sata ports, usb 3.0, thunderbolt maybe, sli/crossfire ready, uefi etc.
then how about the products that available in your city, except you plan to buy online
and what brand that give you better service, since different country would be different too.
i usually put the brand on next list since big brands usually has wide variety of stuff
