Tyrant365 :
What sort of overclock wilI get out of this? Is at least 4.2 Ghz possible?
And will the Z97P D3 be better than the Gigabyte Z87 DS3h and Z87 G43? (obviously with those 2 mobo's i'd be using the 4670K)
Does the Z97P D3 come with SATA cables too?
I would guess that 4.2 GHz is well within reason for this combo. Maximum will depend on your luck in the Silicon Lottery.
If I were buying today, I'd get a Z97 board, not Z87.
Most mobos come with at least 2 SATA cables. Check the manufacturer's website to see if they have a list like "What's in the box" and it should tell you exactly.
