Is it worth overclocking a 2500k for gaming?

I used to overclock my 2500k but stopped when I read something about it having no effect in BF3. However, I just upgraded to a 7970 from a GTX 570 and I'm wondering if that changes anything. Would I get any improvement in frame rates from a CPU overclock?

If you already had it overclocked why bother to lower it back to stock?

You'll probably notice a oc in 64 player mp, but someone else will have to confirm that.

For lower temperatures and less voltage (i.e. to perserve the chip better). I just saw something recently about how the very new GPUs (e.g. 7970) could create a slight bottleneck with a 2500k.
 
Depends on what you play.

My i5 2500K at 4.5GHz would drop to 30fps in World vs World in Guild Wars 2 (with around 60-100 people duking it out) and bottleneck my aged 5850 GPU usage down to around 50-60%. But most games ain't remotely as CPU demanding as that.

I recall seeing a review with a 7970 on BF3, the overclocked i5 delivered higher frame rate than stock clock i5 by like 7fps in their test.
