What processor for gaming?

[Ethan3.14159]

i don't know much about i9 atm, but i heard that i5 and i3 are going to be sold around autumn... not sure yet but i heard that i5 can support dual DDR4...

No DDR4, that's silly. The i5 supports dual channel ddr3. The drawback for the i5 being that in SLI/crossfire the 2 cards have to share 16 lanes, so 8x/8x, or 8x/4x/4x.
