Ok so I'm new to the area of building a pc and don't really know where to start. I have the motherboard and cpu figures out I just don't know where to go from there.

2000 is the limit but I won't mind going over if it means making it better but not by much.
The main purpose is to be playing games not really high end games but some.
I have some parts but nothing that will do me any good.

More than likely will be using online merchants.

Well with $2,000 USD you can easily make a pretty nice rig.

What CPU & MOBO did you have in mind?

MOBO

• Biostar AM3+ 990FX SATA 6Gbps USB 3.0 ATX AMD Motherboard TA990FXE

cpu

• AMD FX-8120 8-Core Black Edition Processor Socket AM3+ - FD8120FRGUBOX

I think it's advisable to instead use a 2500k build or the ivy bridge counterpart if you can get your hands on it. Aside from that, it sounds like you can get away with just a 7870, but that depends on what games, what resolution, and what framerate you want.
