I am picking out memory for my new gaming pc, and i want so get some good ram for a decent price, i am looking at corsair xms2 because i have had good experiances with corsair, and crucial is out of my price range. i was planning on getting either this : http://www.newegg.com/Product/Product.asp?Item=N82E16820145590 or: http://www.newegg.com/Product/Product.asp?Item=N82E16820145034 the first has a cl of 5 with 5-5-5-12 the sec has a cl of 4 with 4-4-4-12 which should i buy? i think the second is better but is it worth the extra $, thanks for your opinions
