If you are going with a 939 pin chip, i'm not so sure you should rule out the opteron 1xx series.

My main gaming rig is a opty 165, single chip on a DFI board. Stock clock is 1.8 Ghtz, but i run it a little over 2.4 ghtz on stock heat sink and voltage. You said you werent interested in O/C-ing , however bang for the buck i cant complain about this opty 165 w/ 20 mins of reading on how to O/C with new board layouts. Under full load this comp runs @ 46C, in a warm room. If you do decide to O/C make sure you read the O/C forum hangouts and manufacturers boards. Some boards do not take well to O/Cing and can shorten the final clock setting. Like for instance some have said ASUS boards with heat pipes dont take to O/Cing to well.

Anyways .... say your guys site on spinhenge@home forums, saw this question asked and thought i would give my 2 cp. Peace, Fester
