And as we see software hardly useses any of the new insturctions (SSSE3, SSE4.x) when not both cpus support it, we'll see the same for the first FMA implementation in BD. At least both sopport AVX so that will get some use.

FMA support is already wide spread in processors and code compilers. C99 supports FMA through the fma standard math library function, nvidia gtx2XX and new gpu's support it, amd's 5XXX gpu's support it, the cell processor, fujistsu SPARC VI, itanium.... BD will support FMA4 and Haswell will support FMA3.

also, windows 7 sp1 will support AVX as does linux kernal 2.6.30
