Which RAM should I buy?

[glenquagmire]

So I am either going with the G Skills Sniper 1866 CL 9 or the G Skills Ripjaw X (Blue) 1866 CL 8. Good brand and least expensive, plus on sale 10% off.

Which will be better and look better in my case?? The Case I think has blue lights in it (maybe someone can confirm?) My board is a Gigabyte GA990FXA-Ud3 (4.0) and I havent chosen a GPU yet.

No need for 1866mhz , get the 1600mhz , you wouldn't notice a performance difference.
