I can confirm that the i3 4150 will be able to run all smash bros games flawlessly, but I can't give my word on any demanding games.
Just make sure you get an H97 or Z97 board with that CPU, otherwise you'd need to update the BIOS (for H81, H87, B85, Z87 and the Q boards). This is only possible if you already have a compatible CPU though.
Consider getting the overclockable Pentium with a Z97 board. You should be able to reach 4.0+ GHz easily with just an EVO.
