Arghh! Someone help me decide on ram!

lol… so yeah. I’m building a new computer and I’m at a standstill on which ram to buy. Both are G.SKILL sets but from different series.

The first is the Ripjaws X series

[LIST]
[] DDR3 2133 (PC3 17000)
[
] Timing 10-12-12-31
[] Cas Latency 10
[
] Voltage 1.6V
[/LIST]

Link is HERE!

The second is the Sniper Low Voltage Series

[LIST]
[] DDR3 1600 (PC3 12800)
[
] Timing 9-9-9-24
[] Cas Latency 9
[
] Voltage 1.25V
[/LIST]

The link for that one is HERE!

Both are 240 pin sets and I feel like the Ripjaws is the better choice because it’s better timing and cas latency than the Sniper. But the idea of a lower voltage also is very enticing to me (and I was going to make the whole thing black/red). However, I don’t know enough about ram to know beyond the voltage helps on overclocking.
But I do know that that the Ripjaws is on sale for $55 dollars (originally priced the same as the Sniper) where as the Sniper LV is $76.
