Do I need a Core i5 for a gaming rig?

[Legolas8181]

I am doing a gaming rig this winter and just wondering do I even need an i5-4670 or would I be perfectly alright with an i3-4130 if I am alreayd going with the £400 GTX 780?

haswells has better ideling power consumption and allmost 3 times faster igpu overall i5 is considered as best gaming cpu i3 as entry level and i7 for extreme

I am deffo getting Haswell but is an i5 really necessary?

that i3 is gonna bottleneck the 780gtx. id say go for a 4670k than sir.
