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.

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
