Need a set of RAM

[chinesekidx]

I'm planning to buy an ASUS M4A89TD PRO/USB3 motherboard along with a 5870 and a 1090T(my preference) for my gaming rig. The only thing that I haven't decided on yet is the RAM. As of now, I'm not planning on doing any overclocking/xfire/sli, but I might in the future. With that said, does anyone have any good suggestions for this particular build? I'm looking for a 2x2GB set of RAM. Thanks in advance.

You need DDR3 for your mobo. IMO you should look for DDR3 1600 (PC3 12800), which will give you some overclocking headroom if you decide to do that down the road. You don't need to look for special low voltage RAM.
G.Skill, Corsair, Kingston HyperX, Crucial & OCZ are some brands I like to use.

Okay I've narrowed my choices down to these 2:

Newegg.com - G.SKILL Ripjaws Series 4GB (2 x 2GB) 240-Pin DDR3 SDRAM DDR3 1600 (PC3 12800) Desktop Memory Model F3-12800CL7D-4GBRM

and

Newegg.com - G.SKILL Ripjaws Series 4GB (2 x 2GB) 240-Pin DDR3 SDRAM DDR3 1600 (PC3 12800) Desktop Memory Model F3-12800CL7D-4GBRH

The second one has a better timing and runs .5 volts less than the first one. Would anyone recommend buying the second one for $15 more for a little bit more of performance or it wouldn't really make a difference?

You're not going to be able to detect the difference between 7-8-7-24 and 7-7-7-24, even with benchmarking software. The higher priced kit is better suited for the obsessive tweaker.
