I used pcpartpicker.com and found out that i5 4460 have some compatibility issues with using ASUS H81M-E motherboard, it needs a BIOS update in order to use the CPU, but when I clicked the i5 4440 it doesn't seem to have any compatibility issues. Is this right? Or my internet is just lagging? There's no need to update the motherboard in order to use the i5 4440?
