Best c++0x compiler?

[Blessman11]

What's the best C++0x compiler out there? gcc or v11? Plus most importantly which one supports multi threaded programming the c++0x way?

I've heard good things about Intel's compiler. Considering they have a software suite called "Parallel Studio", I imagine they've got quite some focus on multithreading.

GCC supports the C++11 threading facilities (except on Windows).
ICC 11 has poor C++11 support, but it's fairly good in ICC 12. Unless I'm mistaken, Intel implemented C++11 multi-threading on top of TBB.

@Athar but it sucks that intel's parallel studio isn't free on windows? (is there even a free counter part to their "pay only" version?)
