So, I decided (so did tsm106) that we should see some comparison results with an identical system.
Below, you will find the system specs, and the benchmarks ran. Yes, its an i3 system, but that's all that ironman86 had on hand to run the GTX680. So I figure we'll bench clock for clock, stock for stock, so on and so forth.
It shows GTX 680's in SLI clocked at 1150MHz. ironman86 has a retail card, and its clocked at 706Mhz at stock (the SLI benchmarks confirm this as well in the GPUz screenshots). So this should give you SOME sort of overclocking idea on how these cards overclock.

Note:
It appears that GPUz version 6.0 shows the GTX 680 to have stock clocks of 1006MHz instead of 706MHz. So my clock for clock results may or may not be valid. Stock vs stock should show a pretty close to clock for clock difference though as they're only 75MHz apart.
GTX 680 System (courtesy of ironman86):
Core i3 2100 @ 3.1GHz
4GB DDR3 (unknown, probably 1600 at 9-9-9 is my guess)
1600x900 Monitor
GTX 680 at stock clocks of 706MHz

These tests might not be EXACT, as I don't know exactly where ironman86 did his screenshots at. But I'll go ahead and do a 3 run Crysis benchmark at the same settings. Should be a pretty close comparison.

i see it near 50 FPS in my third run,cannot deep below 30 FPS.
as a result it much faster than my sig rig, consist 2 GTX 470 in SLI
All three of my Crysis runs were darn near identical except the underclock of the7970 (clock for clock results). This shows that the i3 at 3.1GHz is a VERY clear bottleneck. My i5 with the same card (at 1150MHz) at 2560x1600 actually does a LOT better, I get 45FPS average at 2560x1600, same settings otherwise. See for yourself:

Just give him a second guys, he's obviously going to be giving us 5 entire posts worth of benches and analysis and results here shortly, I mean why else would half of the posts in here be reserved?
No idea, ironman never said if he was single channel or dual channel. However he did say 4GB. And I don't have 2x2GB around here to test with. So I went with the next best thing, 1x4GB.
Also, my benches are on Win7 x64. ironman's was on 32bit. We'll see if there's a difference there or not.
Updated with tsm106's screenshots that I have thus far.
