This card is much more stable than the Gygabyte P55a-UD3R I owned. When properly installed it poses absolutely no problems. 1 negative comment is obliged to improper installation by the customer.
Plus: This board is extremely stable with classic settings and overclocking potential is enormous. Just look Z77A-GD65 in google 3570k overclock in google to be convinced.
Small least: a bracket to deport the USB ports on a equerre in the bundle would have been ...
A very good buy.
