Yeah, like a year after 920 became available? And in certain raw processing power benchs, PII965 is *just* up to the 920. We will see when AMD bring us some six-core stuff, until then, i7 4evar~~...
Back to the topic, like other suggested, run some 3D games with resource hungry engines like Crysis, GTA4... etc
Or else, if you are into video/photo, try some video/photo editing with premiere/photoshop... you would be begging for even more power...
I have pretty much the same setup as u do with SSD in raid 0 for running apps and when I edit 1080P videos from my Xacti HD2000, I still wish for some more.. but anything i7 except the 920 is crazy expensive for my taste... for now, a 920@3.6 would do the trick.
