I recently had two Nvidia graphics cards go pop on me (article here: Link) because of this I needed to replace those cards with a new one. I consulted with a friend who's into PC Hardware and he recommended a few of cards out of the current ATI lineup.

So I bought an ATI 5770, which looked like a good all round desktop and light gaming card.

It is a great card, but it seems there is an issue running it on some of the Nvidia nForce motherboards. The card causes there to be a 20-30 second boot delay. The card appears to spin up a few times, like there is a seek issues with it, then it loads fine.

I've raised Forum topics in both the AMD and the Nvidia forums, but the only solution seems to be flashing your motherboard, which isn't going to happen for me, as I have an Abit motherboard, and they went bust two years ago.
