Asus P8Z68-V Motherboard and RAM Inquiry

Putting a computer together, just need help deciding the RAM.

Motherboard: Asus P8Z68-V Pro/GEN3 - $200
CPU: i7 2600k LGA 1155 - $270
Graphic Card (Intending to play games like SWTOR/BF3): None; Suggestions please; Radeon pref

What is the difference between these two rams?
Corsair 4gb (2x2gb) DDR3 1600 (PC3 12800) 1.65V - $31
G.skill 8gb (2x4gb) DDR3 1333 (PC3 10666) 1.5V - $40

What affect does being 1.65V compared to 1.5V have? I heard certain mobos can't take certain voltages or else it'll fry?
What about DDR3 1600 (PC3 12800) vs DDR3 1333 (PC3 10666)?

With my limited knowledge of RAM, the 8gb G.skill seems better... double the memory for $9 more.
Am I overlooking some small significant details?

Thank You :D

    I bought the very same motherboard a week ago. To not run into RAM related problems, check if your memory is qualified. In any case, if the price difference between qualified RAM and non-qualified RAM is only a few $, I'd always go for the former; in some cases unqualified RAM can work, in other cases it's just a pain.
  2. The ram fits. Coo!

    I have Windows 7 Ultimate.
    My 2 priorities are (5high;1low):
    gaming - 5
    gfx sprites artwork - 2

    Is 8gb RAM overkill?
    Is the Corsair ram faster and have better performance?
  3. If you look at recent RAM speed-tests like you will see that the difference between 1600 and 1333 is negligeable, unless you're running computational fluid dynamics simulations 24/7 - then, you could save a few minutes per day ;)

    In other words, it is wiser to invest into a better GPU than into faster RAM for your type of usage.
