In my country, the Ivy Bridge motherboards are cheaper than Haswell's. Interestingly the i5-3570 ($260) has same price as the newer i5-4570 ($261).
Ivy Bridge,
ASRock H71M-DGS (H61 chipset), $60.
ASRock B75M-DGS (B75 chipset), $77.
Haswell,
ASRock H81M-DGS (H81 chipset), $90
ASUS H81M-A (H81 chipset), $91.
MSI B85M-E33 (B85 chipset), $107
ASRock B85M-HDS (B85 chipset), $112.
It's quite obvious in this case to pair a B75 chipset motherboard with i5-3570 for ($77+$260) = $337. The cheapest Haswell combination of H81 and i5-4570 will cost ($90+$261) = $351. The newer B85 chipset motherboard will be even more expensive.
