I'm building a gaming PC and the video card that I'm getting is the AMD RX 480 8GB. However I have an option between the i5 6400 or the i7 6700. I will be just using this computer for gaming, internet browsing and word processing mostly. With the budget I'm running, I could choose to go for the I5 6400 and use the money I'm saving to get an SSD boot drive. Any thoughts?
