I will recommend get the low profile one-CORSAIR Vengeance 8GB (2 x 4GB).
Becaue you will use the aftermarket cpu cooler most likely, the cooler fan will block the memory if you use the other one. Also the performance between cl8 and cl9 is not difference. http://www.bit-tech.net/hardware/memory/2011/01/11/the-best-memory-for-sandy-bridge/6

Well choose the one with the lowest command rate, that is generally where you are getting juked whenever it comes down to cheaper ram you may see an 1867 9-9-9-24 for $20 cheaper than one at 1867 9-10-9-27 the difference being the first ones running at command rate 3T, and the second one is running at command rate 2T generally all corsair vengeance models run at 2T, and dominators at 1T. That being said a lot of memory modules rated for 2T command rate will run at 1T and be 100% stable, but go for the corsair vengeance low profile I am running 2 of them right now, choose ram based off its frequency rather than its timings though 1867 vengeance usually goes for about $5 more per stick than 1600 sticks, Intels IMC's are so good though that past 1867 your not going to see a huge difference in performance between your 1867 and 2400 modules, anyways here is a link to some good 1867 Mhz memory 6 dollars cheaper than the vengeance you picked out http://www.amazon.com/Corsair-Vengeance-Desktop-Memory-CMZ8GX3M2A1866C9R/dp/B0056KUWS4/ref=sr_1_2?ie=UTF8&qid=1363160417&sr=8-2&keywords=corsair+vengeance+1866
