3 GTX 680's under water

I was pretty impressed as well until I saw the keyboard, only an A++ from me

what's wrong with the g15? what do you use? I haven't looked at a keyboard in about 3-4 years

I'll answer with a picture (albeit, just using the center 30inch monitor now since PLP isn't supported in surround):

Im not a fan of this at all. Because there, the 2 inches gap is no good. I miss the image flow smoothly,, thank you, gl

Hes gonna play @ 2560x1440 , that is what the SLI will allow for. gl

i used to think the same, until I got the setup. it doesn't bother me at all.

I don't treat it as one huge monitor though, I treat it as 3 separate monitors (if that makes any sense). so I don't span stuff across multiple screens

2560x1600 yes... I only game on the center monitor

Badass.

We are running the same fittings, is that also TFC UV white hose ? Wish I had of gone with a bay res like you did. I find my tube res clutters it up too much, and because my PSU is so long I had to jerry rig my pump into the shelf.

I take horrible pictures and I like your taste in colour scheme and tubing/fittings.

What are your serial GPU temps like ?

I am tempted to get a 3rd card just because thermals are so good on these cards, but holding off to see if tri-sli scaling gets improved on the 680 with future drivers.

(these vary on ambient temps)

Idle 29C, 29C, 30C
Load 42C, 42C, 43C (+75GPU , +425MEM ... so 1250Mhz GPU and 3523MHz Memory)

They are nearly ALWAYS all within 1C of each other. My CPU obv is a little warmer

:thumbsup:


So it's hardly a big deal at all. If I let my cards open up in a game like BF3 without a framerate cap, my temps are very similar to yours. I even see a 1C variation between the two and mine are in parallel.

I think your CPU is probably holding you back some, at least in 3DMark. My score is very close to yours. Mostly from better CPU results. Your graphics score is crushing mine, but not by enough. Usually there is perfect scaling on graphics in 3dmark11, at least there was with fermi cards.

Could be a little CPU, but I think it's mostly drivers and sli scaling not carrying over to 3 cards or more.

CPU, being in 16x,8x,16x, scaling (this will get better as newer drivers come out) ... also this:

Not exactly your CPU, but the chipset is what is holding you back. I went from 4.2 Ghz X58 980x -> 4.2 Ghz X79 3930k, and gained ~3k in 3D Mark when I had my 3-way GTX 580 HC2s (and I even had the 580s clocked slower on the X79: 955Mhz -> 850Mhz).

The best i can figure is the latency in the X58 chipset between the PCH (Platform Controller Hub), which was part of the Northbridge, and the CPU. With the introduction of the "Sandy Bridge" chipsets (P67/Z68/X79 and newer), Intel moved the PCH onto the CPU die itself (part of the CPU) to remove that latency.

that was from a member on evga forums had told me.

That could be it. I saw large gains in some games, others I saw none, moving from X58 to X79 with 3x480s. With that move I gained 8 additional PCIE lanes and went from x16/x8/x8 to x16/x8/x16.

I think you could see better results from having PCIE3.0 on X79 as well. The x8 pcie3.0 slot would deliver the bandwidth of your current pcie2.0 x16 slots.

:::drool::: Nice looking rig. Would you mind posting more pictures of it? Exterior, top, etc?

I could, but it's nothing special on the outside. nothing sticks out, on top, etc... it's just a plain old 800D on the outside.

the front however is a little more interesting with the fan controllers, reservoir, etc...

I'll take better pics this evening
