I've used DFI since their nForce2 boards and have never had a problem. *THE* most extensive, tweakable BIOS of any manufacturer and outstanding overclockers. Not had a single one die on me, the nF2 board is still going strong now today.

If you have patience they're one of the best choices for high-end kit.

Yep, that much like my experience. I still have the "fixed" MB sitting in the box as it did not work. I even drove to the repair centre the 2nd time to show them the problem.
Their testing procedure was to run 3dmark for 10 mins

I would never buy a dfi product again

ive used DFI before, and everyone crapped out, dfi will repair when you pay for shipping (no big deal prety much standard practice), well ive gotten some packages back never opened saying the fixed it, some were opened (who knows what they did) unrepaired, then refused to take back a second time to repair, if your looking for quailty products dont use DFI
