Hi, to begin, I'm new here. So if I don't give enough information, tell me. I want to know if a GTX570 Twin Frozr III PE/OC is really that loud as some people tell. If it is, is a HD6970 lightning cooler/quieter? Because nobody seems to know that. I'll SLI the GTX570 so I don't want it to hot/loud. (and I'm a little sensitive to noise because I have no good sound yet. 'll buy it later, first a new pc ) I don't have a hot case because I'll buy a haf X.
