The cheapest motherboard for i5-3470 and GTX 650 Ti are:
ASRock H71M-DGS
ASrock B75M-DGS
Asus H61M
Gigabyte GA H61M
MSI H61M.
Go for the cheapest among these.

Eh, I wouldn't go 6 series just in case the bios that comes with it doesn't support Ivy Bridge.
Good caution though. I only wanted to buy ASRock motherboards because they were the cheapest for the same feature set, so didn't have this concern because ASRock named their boards "H71" which is not an official Intel nomenclature. I got the ASRock B75M-DGS which supports Ivy Bridge processors. ASUS, Gigabyte, MSI still called their boards H61(B3). Good to check with the shop when you buy.
