can u guys take a look at canadacomputers.com all the DFI's i look at , socket 939, it doesn specifically say it supports Opterons, WHAT THE ****, THIS IS SO CONFUSING, and i really dont wanna screw up, im so scared! AAAAH!
If your not overclocking get a Athlon X2. People are going to keep telling you to get the Opty 165 because of it's OC. The 3800+ gives the same range of OC as the 165 but has only 2 x 512kb. This is why if you overclock the 165 would be better, but at stock an extra 200mhz would be better then 2 x 1mb.
