I know the 939 AMD socket has been discontinued and there are not many processors available. The only one available that is retail is the AMD Opteron series or an OEM version of Athlon 64 X2 4200. I am not really interested in building another PC as my current one is only 2 1/2 years old. I was thinking of upgrading from an AMD Athlon 64 3800 to an Athlon 64 X2 4200 or Opteron 185 and adding another 1 GB of memory and maybe a new video card in the future. However will there be much of difference in speed by upgrading the CPU? And if so, which CPU is better? Or should I just upgrade only the video card and memory? I use my PC mostly for browsing, work and some gaming. Please note I am not interested in overclocking.
My current PC is below - any advice will be greatly appreciated

Most(myself included) will probably tell you to upgrade the MB to AM2 or 775 (if you switch to intel). Unfortunately the 939 is outdated and AM2 MBs are about the same price now with far more upgrade options available to the AM2 platform. At most you will get may another year out of the 939 maybe more if you dont game much. You can built a decent new system for under a grand.
