How about no. The 4400 x2 is over my budget and I am already 100 over. But I quess since you are comparing the 165 with a higher chip I think your vote in the 3800+ or 165 is the 165. How high could I overclock the 165 with stock cooling?
With stock cooling prob u can only OC it 200MHz above normal, or ur rig will fry.
Prob with that budget u will need a San Diego Core. Or the opteron 165 will do u just fine.
Lol, sry. Didnt mean to come of harsh. Ya so I hear the Opty stock coolers it is possible to get it to run at 2.8 and very stable at 2.5 so I think I will go with the opty.
