I have owned Crucial Ballistix and the Corsair Dominaror GT's and the Crucial Ballistix performed per manf. spec's and the Corsair Dominator GT's have not. Additionally, I believe the Crucial Ballistix are cheaper. Don't overlook Mushkin, Kingston, OCZ and other high quality memory modules. There are too many variables to say one is better than the other. The higher performance memory narrows down your choices considerably. My memory modules are specifically tested for my CPU. My memory cost over $100 per 2GB stick. Your situation is most likely different and so are many others. Use the MB manf. QVL and do research and then more research before you make your decision.
