Help with my first custom PC

[1timemember]

I'm thinking about building my very first custom entry level gaming PC. I current have an old computer with a GeForce 210 and some DDR2 667MHz RAMS that I like to use on the new machine. Can someone recommend a good CPU and motherboard that are compatible with my current GPU and DDR2 RAM? Also, should I get a CPU cooler as well? Thanks in advance.

With modern motherboard your also going to need DDR3 memory.

I plan to only use it for Dota and League. I don't have any issues running these games with my current OEM PC. I'm looking to make a minor CPU upgrade, but my current motherboard only support up to Pentium D 960.
Any recommendation is greatly appreciated.
