Originally posted by Mantat The best would be a board that allow dual Opteron, just get one now (the cheapest) and after xmast, get rid of the CPU and replace it with 2 dual core Opteron.

I'm not really sure you can do that... as far as I know.. you need 2 CPUs on a dual mobo or it wont work.. (for Opterons at least) but try it.. it might work... I'm thinking of getting rid of this dual opteron PC and upgrading it but now that I wanna buy a car, I guess it'll be ok -Emo
