I'm building a budget gaming PC, and I'd like to know a decent, cheap motherboard. I'm not gonna overclock or anything. It's my first time building a computer. My build so far is:

RAM: G.SKILL KIT 4GB 2X2GB DDR3 1600MHz CL9 Ripjaws PC12800
GPU: ASUS ATI HD6670 2GB DDR3 PCI-E - HD6670-2GD3
CPU: INTEL Core i3 3220 3.30GHz 3MB Socket 1155
Hard drive: SAMSUNG 1TB SATA II 32MB 7200 RPM - HD103SJ
PSU: CORSAIR VS450W VS Series

How do you know which is the right Motherboard?
Oh, and do you think that the CPU is too good for the GPU?
Thanks for reading.
