This is an article I've wanted to do for a while now and as this month started, I told myself it was time to get it done as my testbeds here are making some changes. I've been tossing up if I should make the move to Z68 for our VGA reviews, or stick with the tried and trusted X58 platform. Most people will feel that it's a no brainer with the X58 being the better option due to the fact it natively supports x16 / x16 in dual card setups. For us, that's indeed the biggest draw for the platform; the Z68 one on the other hand has a lot of standout features that make it a better option as well."
The big thing is that the Z68 platform can just overclock so much better. Our X58 / 980X setup is good for 4.2GHz, while our Z68 / 2600k setup is good for 5.2GHz - 5.4GHz. With high end setups, it's so important that we're not CPU limited and even though the 2600k doesn't carry as many cores as the 980x, its +1GHz should yield us more headroom. Read more at TweakTown.
