Hi there archalien. Hope you are well.
RAM - Corsair Dominator 1600MHz 8,8,8,24 3 x 2GB
HD - 2 x WD750GB 7200 rpms for now -- I'll go SSD once the volume goes up and cost comes down. Had a raptor, just didn't see that much gain. No Raid at this time - I had lots of problems with it before, but may try again just for the fun of the pain.
I have the LG Blu-ray/HD drive, but just using a regular one for now. Blu-ray watching is done on my TV(s). Haven't felt the urge to rip Blu-rays yet, but that may come.
Sound - just a simple 2.1 sound system for this one now - will upgrade that once I move it to my new den. Mostly game with headphones so I don't wake the dead.
Display - Dell 3008 30 incher - really too big for my liking.
Mouse/KB - various Logitech products, still trying to find the perfect setup.
Price - Too Much, of course! An approximate breakdown (included all, even though quite a bit was recycled from previous builds):
Case - $400
MB - $300
CPU - $300
Ram - $200
HDs - $300
PSU - $300
Water Cooling Components - $1,000
OS - $200
(BTW ... just ordered components for an i7 rig for my husband - will be air cooled, and the cost was $1,200 for everything except case and HDs).
Why 3 GPUs? Just for fun. Always wanted to do Tri-Sli. Benchmarking is secondary for me, but it was fun seeing 35k+ in Vantage. Runs flawlessly for games. A bit of a help at 2560x1600 with settings on high, but not necessary. Absolutely is overkill.
Noise ... I have a decibel meter, but haven't checked it out. A bit noisy when 11 fans are running at 100%, but I generally run them at 50%. Noise then is a fairly quite hum, not much louder than the ceiling fan. That's the advantage of having all the water cooling.
OC - run at 3.6 24/7 with idle temps mid-30s, GPU temps less than 40 degrees C. At 100%, CPU stays below 60, GPUs below 50. Have taken it to 4.0GHz, still need to tweak to get stability at 4.2. But really don't have a need to run it above 3.6.
So there you have it ...
