What do you use the rig for?
Yo, I use it for gaming, I like by both demanding and none demanding games etc plus 1 rep for replying to thread so soon after i posted
For gaming then an i5 6600 is the sweetspot, you won't get any performance increase from an i7 or overclocking particularly, except for a handful of games.
If you really want an i7, then i guess the 6700 is the one to go for.
You'd have to get a new motherboard also.
ok thanks, would the new motherboard be for the i7? and what games for example would you say need an i7 for best results?
