There isn't an i7-3700. You want the cheapest IB i5 you can get.
Get the cheapest H77 or B75 based board you can if you aren't OCing, or doing SLI/CF.
You want DDR3-1600, CL9, 1.5V, and preferably low profile.
Get something way better than a 650Ti. I'd be looking at a 7870, 7950, or 670.
Where are you (what country).
