You won't know how good they are till you actually test them. PSC were in various revisions and as you can see, these better were mainly in late series ( many designed for SB ) so G.Skill RipjawsX 2133+, Pis 2000 C6, Patriot Vector 5 2400, Dominators GT/GTX 2000/2133/2400 C8 and some other similar series. Even Dominators 2000/2133 are sometimes average.
No one said that these Corsairs on the photo are bad but without tests there is no guarantee there is anything good inside.
