here is my 2 way SLI

 

 
Your overclocks are nice. My boards won't go past 820 (1640)  / 2000MHz or I start to crash vantage.
I'l actually pulled my 4th board for now and replaced the slot with my creative sb card. Once the neccessary patches come out I'll put it back in.
 
An interesting note for my system was that the DX11 drivers that came with the EVGA boards (on the CD) caused BSOD's all over the place. I ended up sticking with DX10 and the NVIDIA certified drivers for now.
 
I'll try and get some pics later today (forgive the mess of the wires, I've not had a chance to tie everthing up yet)

you know...it might be somthing as simple as an nvdia setting..

try using a different rendering method. you have a few to choose from.
SLI mode SLI-Mode setting

Two nVidia graphic cards that are linked in an SLI configuration can work in four different modes:
[class="definition"]Single
This mode effectively disables SLI. Only one card will be used to render the graphics. If a game doesn't work with SLI at all, use this option.
This is also the usual option to be used in the global settings. Since the correct SLI mode is defined in the game profiles which overrides the global setting anyway, there is no need to set a SLI profile globally.
[class="definition"]Auto
This mode tells the driver to select the optimal SLI mode automatically. Unfortunately, this almost never works correctly. It's better to try each of the other two modes, to find out which one works better.
[class="definition"]Split Frame Rendering (SFR)
Split Frame Rendering means that each frame is split into two parts, and each card only renders one of those parts. An automated load balancing algorithm makes sure that the work is devided most effectively between the two cards.
This mode is slightly more CPU intensive.
[class="definition"]Alternate Frame Rendering (AFR)
When using the Alternate Frame Rendering, each other frame is rendered by one of the two cards alternatively. So one card renders a complete image, while the other card is already rendering the following image.
This mode is very CPU effective. In theory, it can introduce a slight lag (i.e. mouse movements are not as immediate as normal), but this effect is so small, that practically nobody ever notices it.
[class="definition"]Alternate Frame Rendering 2 (AFR2)
This is working exactly like AFR. nVidia introduced this setting because it is more compatible with some games.
Since it's just AFR with some compatibility flags set (see below), you can activate AFR2 by clicking the button "AFR2" on the bottom of the list of compatibility flags. 

 
settings like these are in the nvidia control panel.
change a few and see if your fps doesn't get better or worse...

GTX 480 v197.75 ^{BETA is available which ,according to the release notes, now supports 4-way sli's. Please let us know the results of the new drivers. Having my fingers crossed cause I just ordered my fourth 480. And about to order 4th water cooling blocks, fittings and radiator.}
