CPUs are not bottlenecking moderns system, because a lot if not most of processing in games was dumped on GPU (psyx, etc).
To give you an example, I used to have 4-year old C2D Pentium Processor (E6750) clocked at 3.2Ghz. When I upgraded the video card last year from GTS 8800 512MB to GTX 460 the FPS improvement in games (as well as graphical detail) was very substantial.
This year I upgraded my E6750 CPU to i5-2500K (3.3Ghz) and I noticed ZERO improvement in Battlefield 3. So my 4-year old CPU was not the bottleneck. Once I added second GTX 460 to system I saw a very substantial improvemen in Battlefield 3.
From a recent article I read, as long as you have Dual Core CPU clocked around 3.4 - 3.6Ghz it won't bottleneck even GTX580 and above.
This is all from gaming point of view of course, we're not talking about video encoding and things of that nature.

My C2D is clocked at 4.5GHz, and BF3 keep both cores at 100%. In fact, increasing my GPU speed from 1GHz to 1.1GHz gave me no performance increase whatsoever, meaning my 4.5GHz C2D is indeed a bottleneck for my 2GB 560 Ti...It was a general statement on my part. YES - your older C2D most likely would have to sweat like a pig (100% load) to keep up with modern card, bottlenecking it? I would not see FPS boost from doing to 1.1Ghz on card even with i7. Tell me this, do you have HUGE FPS dips or anything of that nature while gaming? I would assume not, even though your CPU is loaded to 100%, it still keeps the game running smoothly.
FWIW, I saw a good impovement in performance in BF:BC2 by overclocking my Athlon II x3 to 3.5GHz, and I'm only running a pair of 4850's in Crossfire. And even now, I experience some slowdowns during explosions and when building collapse.I wouldn't be surprised if upgrading to a Phenom II quad core alleviates the slow downs.
