The I5 4690K should be sufficient enough for gaming. If money is absolutely no issue then go for the I7.Should I go i5 4690k..Xeon or i7 4770k?..
This G3258 is pretty good for emulation. It plays PCSX2 better than my Fx 6300 at the same clock speeds. Specifically while playing Persona 3 FES on PCSX2 there were stutters or slight frame drops at specific spots which was hardly anything to fret over but I notice with the G3258 those same spots don't have drops.
