Totally agree with whats been said. The fact we have someone as skilled as Skinnee exclusive to this incredible forum, taking the hard work out of deciding exactly what hardware to invest in, to me personally is worth its weight in gold.
I upgrade to the latest GPUs from nvidia whenever they are released, and always end up watercooling them with ful cover blocks, everytime I upgrade I have a pair of them aircooled for atleast a month or two. This gives me a chance to break them in, monitor stock temps, see how they behave to overclocking etc and if faults occur I can RMA. It also reminds you of how primitive air cooling is and really makes you appreciate water cooling when you finally do get your blocks on.
Going on the fact I had my GTX 285 2GB SLi watercooled for a year and a half im expecting the same service span out of GTX 480 SLi,
So for me waiting a couple weeks more on air to be told what the leading superior block is, exactly how to mount it (hd video and with TIM or pads) is quite frankly a privilege. Hard to find the words to describe what im trying to get across but I really am grateful someone is doing full blown research on this subject. I want the best for my Fermis and anyone being as patient and waiting for results before they part with their hard earned wages has that garunteed. And know you've made a wise well researched investment.

We love you Skinnee !!
