I'm puzzled why a graphics card would have an impact on reliability for music production. I would have thought that a quality sound card would be the key feature.
My brother runs his own small music studio and uses a relatively low-end ATI card in his system.
I was aware that Nvidia are having problems with yield rates on their development of 'Fermi' but wasn't aware the company is in trouble.
For highish end gaming I'd be looking at an AMD 5850.
