what is the difference between these sets of ram?

i dont see any difference between these three sets of ram maybe im overlooking something?

OCZ Titanium 2x1gb

Patriot 2x1gb

Gskill 2x1gb

the timings, speeds, voltages etc are all the same.....which would be better with this system??

dfi nf4 ultra d

amd 3800+ dual core

western digital caviar 320gb sata II

NEC dvd burner

LITE-ON dvd rom

3-4 Panaflo 120x38mm Ultra High Speed

ThermalRight XP 120

The only real difference is brand recognition and price. Go with the ocz plat rev. 2 or the patriot, not the titanium. You don't want to pay $70 extra for a differently colored heatspreader I hope.
