I'm in the process of upgrading my cpu and can't decide on which CPU to get. I've been looking and I've pretty much decided on a dual core cpu. Kinda fond of the Opty 170 as its a good Overclocker from what i've read and good price. I was also looking at a few others. So When in doubt i ask the pros. I you could have any dual core socket 939 cpu under $400 us what would it be? Thanks.
