It is very hard to answer your question without getting the specs of that motherboard and how high a tdp cpu it will accept. I searched for it and only found asian websites with no english.
The best cpu you could get without overclocking would be the Phenom x4 9950. However, that has a tdp of 125w so I would try to get some sort of info on that motherboard first.
A Phenom x3 8750 is another option. It has a 95w tdp.
There are other options, like the Athlon 64 x2 6400+, but again, 125w tdp...
More RAM of the same specs would help you as well. Make sure they are the same in all areas or get a new kit altogether.
Regarding the graphics card...I don't know if I would put that card in with that power...
