I recently built a new PC for my home office (specs below) and I've been well pleased with the result so far. I'm using the on-board graphics but would like to upgrade (might do some light gaming) -- however, I've gotten spoiled to the almost total silence of the current configuration (the case sits on my desktop no more than 3' from my ears). Are there any really silent (or at least, really low-noise) video cards out there?
