For gaming i like this chart:
http://www.tomshardware.com/reviews/gaming-cpu-review-overclock,3106-5.html
ALL of the following are considered to be roughly equal top tier for gaming:
Core i7-2600, -2600K, -2700K, -3770, -3770K, -3820, -3930K, -3960X, -3970X, -4770, -4770K, -4790K, -5775C, -5820K, 5930K, -5960X
Core i7-965, -975 Extreme, -980X Extreme, -990X Extreme
Core i5-5675C, -4690K, 4670K, -4590, -4670, -4570, -4430, -3570K, -3570, -3550, -3470, -3450P, -3450, -3350P, -3330, 2550K, -2500K, -2500, -2450P, -2400, -2380P, -2320, -2310, -2300
For video editing suggest you look at benchmarks of the software you are using to see if there is a measurable difference between more threads and 'fewer faster threads'. When i switch from an 8-thread i7-920 to a mildly OC 4-thread i5-4690K the newer chip ran handbrake about 30-50% faster than the older, higher thread count CPU. YMMV.
