My PC upgrade? What components should l choose?

[Relja_]

Now I have:
CPU-Intel Pentium E2180 2.00GHz
MOBO-Gigabyte P31-DS3L
GPU-ATI Radeon 5450 HD
RAM-DDR2 1GB
I have 4 GBs(2x2)(NOT USING NOW!) of transcend DDR3 memory.
I want to buy new MOBO(under 50$) which is compatible with this CPU,GPU and RAM(DDR3) and which would be compatible with new CPU(under 70$ and what to choose?).
THANKS!

You really do not have an upgrade path. That CPU is 9 years old, the DDR 3 would not work with any motherboard that would support your CPU. Your system has met it's end.

Save for a new build.

What exactly will your PC be used for? Gaming? if so, what games?
