For backwards compatibility I chose the N650sli-ds4 from Gigabyte. This has, so they claim, especially been designed for durability. Solid caps, more voltage regulators around the cpu than any other mainboard of its class, 2 ide, legacy connectors at the back. It's been simply brilliant in the 9 months or so that I've had it now. Rock solid. I sometimes wonder why I never see any queries or comments about this board here. Either it's so bloody good, that nobody has problems, or else nobody but me bought one. I wonder ..... Gigabyte tried to break into the market by being a cheap manufacturer. Now that they are established, it's my impression that they are trying to make a reputation for themselves by building *solid*, i.e. reliable and robust stuff. I've used plenty of their various cards (video, mostly, but etc) and they've all performed reasonably well or above.
