Which Motherboard is good for 2400 core i5??

Why not? Your cpu isn't designed for overclocking, so Intel is ideal. Their newer boards come with more bios adjustments, which used to be the biggest complaint. And I ask all asus fanboys "why asus". I recommend them sometimes, depending on what's available, but I don't think they're so special. But they do provide more bios updates which can sometimes extend the life of the board as cpus change. If you want to spend more, look at some z68 chipset boards, or wait for Ivy bridge and see which old boards will get a bios update from their manufacturer to use the new cpus.
