If you have a CPU Cooler that doesn't hit Ram Spreaders, then go for the Vengence. (3rd Link).
They're pretty much all the same, should support your system and 1.5v low voltage helps for Sandy Bridge.
If you could find anything better around the price range (~100) with lower timing (8-8-8-24 & (7-8-7-24), you would get more Performance from those. But they are more expensive especially if you're looking for 16GB's of ram.
I hope you play more than games...or else 8GB's of those are wasted.
Thanx, I dont play games, just CS5 stuff : )
