Thanks for the input willibj as well as everyone else who has replied!
You would definitely need a new motherboard, and probably RAM for good measure (given that 1366 is triple channel and 1155 is dual channel - and you'd want to sell your old CPU/MB/RAM as a package) if you were to upgrade. I think you'll find that any cooler that works on 1156 will also work on 1155 (thus Dark knight would be fine), but don't quote me on that
The Dark Knight would also handle Sandy Bridge up to 4.5-4.6ghz easily. But I digress, and we are discussing the cheapest component in question, and it's thus largely irrelevant.
I think you should double-down on trying to overclock your CPU properly whilst you wait for GTX680's to come out. Take your time and do it step by step. If you find that your Dark Knight isn't handling things well, you could always upgrade your cooling to handle a better overclock on current hardware. And yeah, save you money for a new GPU and for college mate.
You never know, simply overclocking your current rig stably might give you all the performance boost you need to tide you over. In all honesty, your current rig is pretty beast - it could do with a solid overclock. If you had it running under water, you could probably overclock your GTX480 to GTX580 levels, and your CPU could get at least a 50% increase, all whilst running cooler and safer.
TL:DR - learn to overclock your CPU and GPU properly, and maximize your current rig first - THEN decide if you really need to upgrade at all
