yeah, amd discontinued the 1xx 939 opteron line, because a 2ghz opty with 1mb of l2 cache was cheaper than an athlon 64 2ghz with only 512k of l2 cache, and they were selling like mad, and i guess amd was losing money. not to mention they overclocked like gods. good thing I got mine when I did. Look for a dual core opteron 170 if you can find one, and then a 175. If you can't find any of those, I guess a 4400+x2.
