In that case, he should just get an i7 then.
Ok pat check which i7 would be best.
Like I mentioned amd quads and hexas are very good at balancing things
If that weren't the case I would have got rid of my fx4100 much sooner
With that gtx770 16gb of ram you or he wouldn't even need to dream about Intel.
I still think it would be a waste of benjamins for a CPU upgrade only.
