I am considering upgrading to the 4000+ San Diego from the system listed below. I am also considering the 4400+ Dual Core. Would it be bad to stay with a single core? And will I get any considerable difference in performance? I just recently upgraded my ram to 2gigs OCZ so I'm not really interested in waiting for the AM2 version. Which I believe uses ddr2 but I could be wrong. If I'm wrong about AM2 let me know, which I'm sure you will. Any advice would be appreciated.
I would save your money for now. I doubt you would see enough of a performance jump to justify getting one.
Once the M2 socket cpus come out the price of the older cores should come down quite a bit. By that time hopefully there will be alot more games that will take full advantage of an X2. Thats when I plan to upgrade.
