Whoop...

No it's more than 40% faster, not just a few but many tests show above 50% difference. Alot of them are at 60-70% so it's quite unreasonable to give it a 40% number. 40% seems like a minimum difference.

Plus one of the highlights of sandy bridge is how much it overclocks. On average a sandy bridge CPU will edge out a phenom by 600-700Mhz which I believe would actually make it double the performance core for core.

I wasnt even aware that the turbo boost only happens for one core and in multi-threaded applications it's quite useless. That makes it even more absurd to not overclock it as you can essentially gain a Ghz with just automatic settings and if you are willing to put in time you can reach even higher.

The sandy bridge core is about 40% faster....the math aint that hard to do, look carefully. In most apps the phenom II is about 30% behind and in most games (RTS games) the phenom II is about 50% behind, taking the average is around 40%....im not sure where you're getting a 60-70% number from. When you oc it probablyl is around 70% faster, thats assuming you get a really nice overclock. But were not talking about overclocking here, only the architecture and from the benches which you urself posted, sandy bridge is about 40% faster core for core. Anyways sandy bridge isn't really necessary for gaming, anybody would be fine with a phenom II. I myself realized that a little late, but im still happy with my choice.

67% difference in photoshop. Thats pretty big, not every benchmark has the same weightage not for me anyways. Again 65% difference in some 3dsmax r9 thing. Several benchmarks of this and the difference remains big in most of the time. Then some par2 thing has 67% difference.

93% difference in microsoft excel 2007 SP1 which again constitues a pretty major program. 62% difference in WOW.

I have no doubt a 4.5Ghz 2500k would be twice faster than a 3.8Ghz phenom II X4 which represents the average easy overclocks you get on the chips.
