Looking to upgrade my system, and was confused between these two CPU's. I have just enough money for the CPU, along with a mobo. The problem is that if I get the i7, I'll have to get a lower end Z97 mobo, while with the i5, I'll have enough to get a higher end mobo, like an Asus VII Ranger. What should I get, between the two? I'll be gaming on an 1080p monitor. I want to future proof my system for a good 2-3 years.
