Im looking for the Quietest GPU with the Best Performance

My budget allows me to get a GPU for at the very most $310. Here is my setup right now i have everything except the GPU, so I'm not planning to change anything else.

I'm looking at Radeon 7950s. I have a $20 Newegg gift card if the price is a little bit over $310. Thanks in advanced.

Any GPU from either ASUS, Gigabyte, or MSI will be pretty quiet. Sapphire cards are relatively quiet too. The noise level depends on your environment (temp wise) and the stress you put on the card really.
