if not, what should i look for?
Yes it is possible for the most part, you just need to tweak around with the voltage and even some of the power delivery options in your motherboard. I'd also like to point out that as with all CPUs, sometimes you get ones that don't OC as well or even very poorly in some circumstances. This isn't your fault, and some people like to call it the silicon lottery, as some chips are better than others when it comes to OC'ing the voltages needed to go that high.
For example, my i7-3770k is currently doing 4.7Ghz at 1.23v
It has been stable for almost a week now, and I'd say my chip is "good" seeing as a lot of people need more voltage than mine to get it up and those speeds. Your mileage might vary, because not every CPU requires the exact same amount of voltage to OC it to the clock that you want it to. So my point is, experiment with voltages of 1.2v-1.26v for 4.5Ghz once you do get your Ivy and its motherboard. Just have some patience with it all.
And yes, an i5-3570k @4.5Ghz is more than enough for 2 680's - you'll smash through any game easily. I can't think of any bottlenecking going on between those 3.
