With all due respect, I totally disagree... from my own experience.
The second RAM set does not fully clock on AM3 boards without a ton of work and testing, and even then doesn't quite make it all the way in many cases. The first set is utterly overpriced. I would recommend the F3-12800CL9D-4GBRL. Another set of G.Skill Ripjaws ($93 shipped) 2x2gb PC3-12800 (1600 Mhz).

If I would do my system again, buying that RAM instead of the f3-12800cl7d-4gbrm would have been one of the few things I would change.
