I'm building my first gaming PC and after research I found that an i5 processor will do the job just fine, but I read some stuff about DirectX 12, which says it might need the capabilities of an i7 processor, but I don't know the veracity of those claims. I don't really mind paying the 100$ or so more to get an i7, but I don't like spending money for nothing either.

If it helps what I plan to build is : http://ca.pcpartpicker.com/p/d9vjxr

All in all what will DirectX 12 change for the CPU ?

Thank you in advance.

DirectX12 will reduce CPU load and spread it out more. Since the I7 has hyperthreading it might become somewhat useful. Vs right now where there is no point to an I7 for gaming. It certainly does not need an I7 and I would not recommend one.

There's this misconception that DirectX 12 is almost entirely GPU focussed, it's not, it's almost the complete opposite. With DirectX 11, the CPU could only schedule one task at a time to the GPU so developing a well multithreaded game (for instance) would make the task list very long and then you run into optimisation issues.

With DirectX 12 we now have parallel processing and the CPU is able to schedule multiple tasks for the GPU. The more cores and threads a CPU has, the more parallel capability IF developers optimise for it.

AMD GPU's should perform a lot better with DirectX 12 (in theory) because of their ACE technology.
