Who cares about Super Pi anyway :
It depends more on core speed then core count.
Super PI is single threaded, so its relevance as a measure of performance in the current era of multi-core processors is diminishing quickly. Therefore, Hyper PI has been developed to support multiple threads of Super Pi to be run at the same time so you can test stability on multi-core machines.

Anyway, benchmarks only influence your decision but are mostly irrelevant because, like cascade9 mentioned, they don't reflect what a user will do with his system.
Every user has different needs whille system A will be faster one user it might be slower for others.
Personally I prefer AMD because they seem to have more democratic prizes and less bulls**t.
The reason I don't like Intel is the same why I don't like Microsoft, I don't like how they run things and their attempts to monopolize everything.
I remember a few years ago when AMD lauched the first desktop 64bit CPU, Intel didn't have one so they just took their 64bit XEON, overclocked it and switched of ECC because it was having troubles when overclocked. I think it was the guys from Tomshardware who found out about it.
It took Intel years to finally see the benefit of incorporating the memory controller into the cpu but meanwhile they claimed "our cpu's run cooler", of course they do when you have less stuff in it and move it to the MB chipset.
Oh well, there are stories like that about AMD, but the 64bit story was abit too much imho.
In the end it also comes down to buy something that you feel good about.
If you want to buy a certain brand even though it's not the best, who cares, it's your money.
It doesn't make sense to buy something that you don't like just because others said you should buy that.
What's the point to have a state of the art system if you don't like it for some other reason?
