I must say you made a very good choice.
The prices are very reasonable for both CPU and Motherboard (CPU Costs $225 and Motherboard costs $ 145).
Go for this build. Remember to overclock the CPU (Purchase a good cooler too).
The motherboard is one of the best and most durable motherboards out there. I would suggest this configuration to anyone out there due to high overclocking capabilities of Ivy Bridge which makes it somewhat better than Haswell counterpart if overclocked correctly.
