Scott,
I still use a dualcore wich suits my needs. I am quite sure a 6 core will be more than I need. So other things matter more. Stability is offcourse the main thing. I allso need a mobo with at least 3 or 4 pci slots.... And around 4GB memory would suffice...
You know two years ago most DAW's were not able to take advantage of more then 2 cores. Now to be able to own 6 on one chip is exiting. I still am not sure (seen proof of) that DAW's know how to benefit fully from 4/8 or 12 core's. So one chip & 6 cores for such a low price is exiting...
Just have to investigate some more.
Recently I went from XP to Vista64 to W7 64. And my DAW gained responsiveness. So my X2 is now I think 10% faster. With 20 tracks & alot of plugins this matters. Within the limitations of this system. & it is still very reliable and so on. So that 6 core will probably blow my mind.
