Newbie at motherboards ...

So guyz, i'm looking foward to upgrade my CPU, but because my motherboard is kinda old, i can't go really far. I want to upgrade my MOBO first but i'm a total noob as stated before so can u guyz help me find the right motherboard.

I want a cheap AM3 motherboard that will support my AM2+ AMD X3 8450 and my RAM, i'm kinda confused about the RAM i already have, here's a picture of it:

I wanna keep my CPU and RAM for now, because i recently upgraded my GPU and don't have enough $$$.

So any recommendations plus the recommended yet cheap motherboard will be highly appreciated ...
