Hello, I was wondering if anyone could find a CPU, quad core preferably, to replace my old Athlon 64 X2 5000B that came in my Optiplex 740. I have searched around and can't find much, since there are no more CPUs that don't have Am3+, which is incompatible with the AM2 socket. I would also prefer if it was an AM2 socket, not AM2+ or AM3, as even though they are compatible, I don't know if they are supported in the BIOS. That's all, thanks for any and all help.
