I can't really say how good crucial is. I have two sticks of it, but I need to RMA them cuz they're messed up so I haven't been able to use them to their full potential like OC'ing, etc. I had stock timings of 2-2-2-8 though and they are supposed to be in like the top 5 for ram out there (although there has been so much more ram put out recently I dunno where it would stand).
Ballistix ram Rocks, have two in my Computer, I dont feel bogged down at all great choice ban, and ill tell you if i can OC them when i get the chance to let you know i will.
