A couple of questions. 1. How noisy is the 5770? 5870? compared to the Nvidia GT 120. I'm not concerned about under heavy use, just under idle conditions. If you've owned a 2008 Mac Pro, how does the noise compare? 2. What exact model is the 1 TB drive with 32 MB of cache? I'd like to upgrade my hard drive and was wondering which ones it is so I can just order the exact one from New Egg. Thanks!
