Hello!
I have i4570 (6mb 3.6mhz)
GTX 970 G1
Kingston Fury 8 gb (1886 mhz)
Z87-G45 MSI
and I can say that , this cpu is good for it price,but if you get some K processor with hyper-treading tech. it will be better.
I run FarCry on ultra( with only AA is on AASX2 ) cpu load is up to 70% but not all the time,The Crew - same happens , Alien Isolation - 50% load , BF4 - 75% load.
and whatever processor you get , be sure to buy a good cooler ( stocks cooolers are so bad this days)
I use Deepcool Lucifer idle temps are 24-27 C load (100% ) 53-55 C
Conclusion:
Great processor for it's price, it gets the job done but in 2-3 years you may need faster one.
