    Here is some information to compare the two:

    The Jun 1979 Popular Science Magazine reported the Cray-1 Supercomputer cruises at 80 million operations per second. With overlap calculations approaching 140 MFLOPS and burst calculations at 250 MFLOPS.

    Based on Intel's numbers
    (http://www.intel.com/support/processors/sb/CS-023143.htm) the i7 975 2.66GHz runs 42.5 GFLOPS and the i7 975 3.46GHz runs 55.36 GFLOPS.

    So...

    80 MFLOPS vs 42,500 MFLOPS or 55,360 MFLOPS depending on your processor.

    Nice build!

    We have a real Cray-1 used as a couch on campus, put there by Cray research a bunch of years ago, and it's a lot more interesting design than a regular 19" rack cabinet at least =)
