It means your CPU is to slow to keep up with the graphics cards, I've seen this is many reviews where you performance just hits a wall, your Q6600 is a larger bottleneck for your faster more capable graphics cards. You need a faster CPU to push those cards further than you are now, you are at a brick wall as far as getting anymore performance out of your cards because the CPU is holding everything back which is why you gain so little FPS when you lower your settings.

Your Q6600 isn't going to give you anymore performance, its very near its limits as it is being 4 years old. I'm in exactly the same boat as you my friend, an E6600 paired with a GTX 480 makes me laugh now that I think about it! My E6600 was just barely enough to properly push my older 8800GTX to its full potential! Would you believe that in almost all of my games (Mass Effect 2/Crysis) when I changed out my 8800GTX for the GTX 480 my maximum and minimum frame rates stayed exactly the same between the new and older card, can you say CPU bottleneck!

I just want to make sure 100% that this is a CPU bottleneck before I buy a new CPU MOBO and RAM for my computer, seems like $450 minimum investment if I want to go Sandybridge, realistically probably $600.

Have a look at some websites that review graphics cards and you should see that sometimes in certain games all cards regardless of how powerful there are will hit a wall performance wise, there hard to find but there out there and will show you CPU bottlenecks.

Thanks for the link I'll look around a bit. By the way, is there anything that shows that Sandy Bridge will bring better performance/less of a gpu bottleneck in video games? I'm just wondering how beneficially it is to wait for SB instead of just picking up current i7 hardware.

After looking at this article I'm more confused than ever. At the higher resolutions, the cpu bottleneck seems to vanish. Is this really my problem?

Expect Sandybridge to take things further and I say this because they have managed to overclock a Sandybridge CPU on air cooling to 4.9GHz using four channel memory and thats early silicon! When Intel's Nehalem (Core i3, i5 and i7) first came out it didn't do much for games at all at launch, thats because games didn't utilizes four cores and wasn't opitmised for the gaming platform. I fully expect Sandybridge LGA2011 to take things to the next level with multi-GPU gaming, but Sandybridge will be better in the long run just as with Intel's Nehalem CPU, more and more games with start using all four cores and with crazy overclocks like 4.9GHz on air cooling and things look very bright indeed!

You are not running a GTX 280 with is slower than your GTX 470s, you can't compare the two because your 470s are faster than the GTX 280s! Multi-GPU Fermi based cards run much better on faster overclocked quad cores, something you and I are lacking!

Update, from your link you provided

Last but not least, Crysis Warhead. Again, both the E8400 and even QX9770 stumble into pretty hefty CPU limitation whereas the Core i7 keeps on steaming.
You don't even have the QX9770 CPU so you are far worse off with the Q6600!

3 x 280's is close in performance to 2 x 470's for sure. And my q6600 is clocked much faster than that QX9770.

Clock rates are one thing, CPU design is another! Clock rates alone doesn't tell you anything about CPU design or how it works internally, with the QX9770 clocked slower than your Q6600 it is indeed faster even at a lower clock rate. You can overclock your Q6600 to 6GHz and it still won't come close to a Core i7, it's all about CPU design!

In response to your 32bit to 64bit installation of Windows 7 only programs and/or games that take advantage of 64bit will you see a difference.

Yes, the the higher the resolution the higher the demand on the GPU. That's why they lower resolutions to 1280x1024 to test CPU differences. If they had dual/tri 580s, the 2560x1600 would be less and less bottlenecked by the GPUs making the only thing to improve framerates at that point a faster CPU.
