Performance wise,which is the best Ram out of the following?

Option one is:
CORSAIR XMS3 DDR3 4GB-1600BUS 2Gx2 (CMX4GX3M2A1600C9)
OR
CORSAIR VENGEANCE LOW DDR3 4GB-1600 2GX2 (CML4GX3M2A1600C9)
The only reason im preferring these is b/c they are dual channel and i read somewhere that 2x2GB will perform Better then 1x4GB module on a Dual channel board.
In case that is NOT true,i can get either of these:
CORSAIR VENGEANCE DDR3 4GB-1600 4GX1 (CMZ4GX3M1A1600C9)
OR
G.SKILL Ripjaws Series 4GB (1 x 4GB) 240-Pin DDR3 SDRAM DDR3 1600 (PC3 12800)
I prefer Ripjaws b/c it has lifetime warranty,all the rest have either 1 year max or 3 years,not sure.
Suggestions needed quickly pls,will be buying one of these in a few hours at most.
Ohh And i only watch movies,Play Games like BF3 and browse the net. Thats all i will be doing on these rams.

Ensure your MOBO can take these 1st, goto the MOBO website and check the QVL. Then i would go for the one's you like the look of as there pretty much the same. But i would got for 2x4gb if your OS can take it (64bit).

Motherboard is Asrock B75m so it can probably run all of them. Yes OS is 64bits too. IF there is no performance diff then i prefer Gskill
