Sounds good...2 x 4 GB...
While you are correct, there is not much advantage in having ram faster than 1333 Mhz for your intended primary purpose of gaming, there is still some advantage to faster ram ( overall system performance and certain apps that are memory-bandwidth sensitive ). Since ram is fairly cheap these days and 1600 Mhz kit costs the same as 1333 Mhz kit in general - at least here in North America it is very affordable ( very popular ) , why not go for the faster ram... you would not notice the difference between 1333 Mhz and 1600 Mhz in most cases ( gaming ) but might as well get the fastest ram you can afford within budget...
Too bad you have to pay nearly double the price we pay for ram:
http://www.newegg.com/Product/Product.a ... 6820233144There is nothing wrong with the Kingston 1333 Mhz 4 x 4 GB kit ( 16 GB total ) you listed, but since the Corsair Vengeance 1600 Mhz 2 x 4 GB ( 8 GB total ) kit you listed only costs $3 more ( from where you are buying it from down there ) , then why not splurge and get the Corsair ram...only $3 and 8 GB is more than enough for just gaming use..that way when you add another kit of the same down the road ( when prices drop or you find it on sale in Brazil ) to give you 16 GB total, you will have it all running at 1600 Mhz together...4 x 4 GB sticks... or perhaps 8 GB will be "enough" for your gaming needs for the lifespan of this computer...but the option is there of course to add more am if you feel you need it.. current games barely take advantage of 2 GB ( since they are mostly console ports ) and this won't change till the Xbox 720/Next is launched Christmas 2013... so 8 GB is kind of overkill if gaming is the most stressful thing you will use your computer for, but sure does not hurt to have that much if you are a heavy multitasker or plan to do a bit of Photoshop work etc ( loves lots of ram ). Cheers! ( I am still running 4 GB of 1333 Mhz here, will get 8 GB of 1600 Mhz kit ( or faster depending on price of course ) when I upgrade my whole system eventually, but for now even 4 GB is "enough" for all modern games, never run out of ram while gaming ).
Also, do you intend to overclock your cpu at all? It is recommended to have higher speed ram to match an overclocked Sandy Bridge or Ivy Bridge cpu... it helps in overall system performance/memory performance to have higher speed ram especially if overclocking these families of cpu...
http://www.tomshardware.com/reviews/bul ... 09-13.htmlStill, the best reason we can think of to buy high-end memory is to show off a big overclock.
Since high-speed memory only provides a marginal performance benefit to a small number of all the applications on your PC, we can only recommend the step up to a subset of enthusiasts willing to pay that extra money. At the end of the day, you will need to be the judge of whether or not the added expense is worth the marginal performance increase.
So tiny performance gains ( if any in some games , more in others, 3DMark 11 is a synthetic benchmark so you have to take its memory results with a grain of salt ) , but still gains!!
Still recommend 8 GB ( 2 x 4 GB ) Corsair 1600 Mhz over 16 GB ( 4 x 4 GB) of Kingston 1333 Mhz for your intended purpose of gaming, but go with whatever you think is best, either way you will still have a fast system... but if you intend to overclock your cpu then definitely go with the faster speed ram of course...EDIT: He is buying a "non-K" cpu so cannot overclock cpu anyways...never mind that point then..
Too lazy right now, will reply later my young Padawan!
