Well, can you post a screenshot of CPU-Z as well? That might be a little more helpful.
From what I can see, your mobo is a socket 478 motherboard.
Socket 478 as of now is an antiquated socket. It doesn't even handle 64-bit applications!
What is your budget to upgrade the CPU/GPU?
If high enough, maybe you can get a new system for the same price, with better performance!
