No worries. I'm not taking sides either. Sandforce have a random BSOD issue that would worry me - especially since if I were speccing a new system I'd get the Asus Z68 Pro which is one of the boards demonstarting this occasional problem. As for degradation I need to read up on this. I'm just glad I got a Vertex 2 before 25nm was all that common. Had I known I would have bought a few more. It's not often the previous year's tech beats the current year's.
