If you're talking about performance in terms of higher clock speeds and lower timings, then most companies offer premium versions of their RAM that will perform better in that sense.
Examples: Kingston HyperX, OCZ Titanium/Platinum/Gold, Corsair XMS, Patriot eXteme performance, Crucial Ballistix, Geil Ultra, any Mushkin perforamance series
If you don't plan on overclocking or tweaking your memory timings, you might as well go with the regular version from any one of those providers, like Kingston Valueram for example. You won't notice a difference in performance.
