    So why the Westmere-EP vs. The i7-980X?

    It looks as though the Westmere-EP is pretty much identical to the i7-980X so why use the Westmere in the Mac Pro vs the i7?

    X5680 is not even used in Mac Pro. It's W3680 what is used in 6-core Mac Pro. It costs 999$ in 1k lots, the same as 980X costs.

    I edited it to reflect the correct chip... Is there any major benefit to using the Westmere vs the i7? Is it because the iMacs are using the i7?

    Xeons support ECC memory which is important for some people as MPs are workstations.
