upport CPU:
SSE3
    * AMD Athlon 64 X2 (All revisions) - Reports only one cpu, shows 2 activity graphs
    * AMD Athlon 64 and FX (Venice and SanDiego only)
    * AMD Turion 64
    * AMD Opteron (Troy, Italy)
    * AMD Sempron socket 754 (Some new Palermo revisions do support SSE3 and AMD64)
    * Intel Celeron D
    * Intel Celeron D 345 j+ (3.06 Ghz)
    * Intel Pentium 4 (Prescott)
    * Intel Pentium D - System Profiler reports one CPU, but activity monitor shows two. Seems to support SMP.
    * Intel Xeon (Nocona, Irwindale) 
SSE2
    * AMD Opteron (sledgehammer)
    * AMD Athlon 64 and FX (newcastle, clawhammer, winchester, barton)
    * AMD Sempron socket 754 (K8 based)
    * Intel Pentium 4 (requires SSE3 patch for Rosetta) All SSE2 CPU need a patch for Rosetta
    * Intel Pentium M
    * Intel Celeron D
    * Intel Celeron M
    * Intel Celeron (Williamette, Northwood)
    * Intel Xeon (P4 based)
    * Qemu Virtual CPU 0.7.1 (slow, emulates SSE2/EM64T) 
Unsupported CPU
    * Intel Xeon (Prestonia) - Crash on Extention Archive doesn't contain software for this computer's CPU Subtype - Explain us
    * Intel Pentium III-M
    * AMD Sempron / Xp / Socket A (462)
    * AMD K Series
    * Cyrix (Just for kicks I my OSX harddisk in my ancient closet-box. No dice, sadly.)
    * AMD K6-2 Series
