Extreme4 is good as a budget and cheapest I'll get with a k series CPU but I wouldn't put anything beyond a low end air cooler on it, the VRMs on the UD3H are better quality and it's sort of a mid-way point between Extreme4 and P8Z77-V and other high end MBs. Often the UD3H is only $15-20 more expensive than Extreme4 as well, it goes on sale too. UD3H $148 and Extreme4 $130, or $135+RAM (note it is a single 8GB stick meaning it'll be running in single channel, the fins also prevent the use of high end air coolers)
