Because he didn't specifically say he was going to buy ONE 16 GB. RAM kit and many people make the false assumption that they can just buy (2) 8 GB. RAM kits of the same part number and run them at the advertised latencies and frequencies of ONE RAM kit, which Corsair specifically states may NOT be the case.

In addition it's easier on the IMC to use (2) DIMMs over (4) DIMMs. Some mobos also limit OC'ing when (4) DIMMs are used forcing the RAM to be run at the default frequency for the CPU.

The bottom line once once again is that mixing of RAM even of the same part number can have issues, i.e. could require slower latencies or higher voltage than a ONE, matched RAM kit of 16 GB.

As far as recommendations sure everyone has an opinion as to what is "Best" based on THEIR definition of "Best".
As far as the Asus Crosshair is concerned any DDR3 rated for the CPU brand you are using *should* work but in reality that is not always the case and can vary by mobo/CPU or RAM Kit. You can always e-mail Asus and the RAM maker before you purchase to see if there is any known issues with the RAM you decide to purchase.
Since the color Red and Black seems to be part of your definition of "best" your options are more limited.
Geil offers some Red and Black as does Corsair. Numerous RAM suppliers offer black RAM.
If you are going with 16 GB. I recommend ONE 2x 8GB. RAM kit as long as it's competitively priced with ONE 4x 4 GB. kit. Mixing of two RAM kits - per Corsair does not guarantee that the RAM will in fact run at the advertised frequency or latencies of a single RAM kit.

By best I mean the best performance in terms of speed and efficiency. If it is better to buy 2x8GB, then that's what I'll do.

So I think it's gonna be a toss up between:

http://www.newegg.com/Product/Product.aspx?Item=N82E16820231528

and

http://www.newegg.com/Product/Product.aspx?Item=N82E16820233277

What do you guys think?

Can anyone tell me if the corsair is worth the extra $50?

Any other recommendation are welcome.

No the Corsair is not worth an additional $50. as the two RAM kits have identical latencies and frequency.

No one knows how any RAM kit will OC with your mobo/CPU until you test it. I'm not sure what your definition is of "efficiency" either... biggrin.gif These two kits are rated the same including voltage.

Be sure that you have HSF clearance for the top mounted RAM heatsinks.
