I'm sorry but I have to disagree completely with that the i3 will struggle , See the frame variance in 64 Man server ( no sign of struggles at all ).
I know what I am talking about ,
Rock Solid sir , i3 won't struggle at all as in fact its a very decent choice and the difference between it and the i5 is very minimal .
Also here in MP 64 man servers no sign of noticeable frame variance over time with the i3 ( older gen , weaker and the latency isn't killing the performance also its coupled with a titan so in real world terms coupled with 270X no performance dips will occur ).
