I think I want to purchase a 4820k CPU. Originally I was looking at getting the GA-X79-UP4 but I've read there have been functionality problems with the bios. I've also read that some mobos just won't overclock with the 4820k because of bios issues as well. What mobos would be compatible/work well with the 4820k? My budget including the CPU is about 480 USD, and I know I can get the 4820k for 270 USD, so anything either in bundle or by itself for <~220
