I’m thinking of upgrading my CPU (it’s only a couple years old, but still, there have been some major advancements.) The motherboard’s a socket 939 and I don’t really want to go replacing that as well, because if I do that I’ll wind up having to replace about three other pieces of hardware. This should list all compatible CPUs (I might have to flash my BIOS, but no big deal, besides it’s got the backup BIOS on the motherboard). I assume I want to get a dual core and it has to be a 64-bit processor (not that I’m using a 64-bit OS to take advantage of it, due to lack of drivers.) I’m currently using an Athlon 64 3500+.
I guess my real question is what’s the difference between the Athlon 64 x2 processors, the Athlon 64 FX processors, and the Opteron x2 processors. And considering the age of my motherboard and that it wasn’t really built with the newer CPUs in mind, what would be the best choice?
