So I decided I wanted something more powerful than my 3570k and 660s, so I came up with this monstrosity.
The PC can get a bit loud while gaming (~50db) mainly because the ACX coolers are LOUD (maybe i just have a low tolerance for noise, as almost every review describes them as "whisper quiet") above 50% and my cards tend to sit at 55%-57% rpm under max load.
I also plan to change out the stock radiator fans with some Noctuas to further reduce the noise.
Overall, I'm really impressed with the system and my near 19000 firestrike score (sitting at 18322 before CPU overclock and haven't run it again yet). Certainly a hell of a step up from my old rig's ~7800.
