Exclamation Fast system yielding inexplicably slow game performance - what gives?

I built a really sick system (I've been building machines for over 10 years) in preparation for Battlefield 3 and Ghost Recon Future Soldier, both perform painfully slow, yielding framerates in the low teens and even sometimes dropping down to single digits

Taking a look at my components below (i7-2600K 3.4GHz, GTX 580 GPU, G.SKILL 8GB RAM...), and looking at benchmarks from around the internet, I am not getting the performance I would have expected. (I have all the latest drivers and firmware on all of my components.)

Interestingly, the poor performance is always accompanied by crackling / static sound in the game audio. I've also tried removing my Xonar DX pci-e sound card and using the on board sound, but the same performance problems occur.

Notably, other games that are a couple years old (Bioshock 2, Dead Space 2) run just fine and at the high performance that I would expect.

The only thing about my specs that I am beginning to suspect as a bottleneck is the PSU (4 years old NeoPower 650). I had always been under the impression that with a PSU, it was all or nothing - meaning that, if my PSU couldn't handle it, my machine wouldn't run at all.

Could the PSU be choking game performance without just shutting my system down completely?
