Correction of the above comment there is no huge performance boost or improvement by switching to haswell platform the last line which is realtek ALX1150 7.1 channel audio.
what has intel done in 4th gen i3 is up the level 3 cache by 1mb n increased the clock speed to sweet 3.6Ghz but charges 160$ for this chip. this is like slightly beefed up version of the core i3 3240 which is highest clocked core i3@3.4Ghz n the i3 3220@3.3Ghz both r fairly priced@130$. if u r currently running the ivy bridge chips n want to upgrade to haswell? no there is huge performance boost or improvement in haswell but u want switch u have buy the haswell chip first n then the LGA 1150 socket mobo cuz haswell doesn't sit on LGA 1155 there r cheaper mobos like H81 for core i3 these r entry level basic boards offers nothing similar to older gen H61 series of mobo's just run of the mill boards.if u want to look at some good boards H87 series these r non overclocking mobos n the B series of boards are also for everyday business computing offices. the best mobo for haswell platform is Z87 series which is more than 90$ but offers cool sata 6Gbps 6-8 ports n 4 usb 3.0 n 2x usb 2.0 n supports Nvidia SLI n AMD crossfire support n realtek ALC7750 7.1 channel out of the box.
