Those of you interested in the i7 platform know Triple Memory is the way to go. We look at Corsair's i7 Dominator and compare it's performance in 32-bit and 64-bit Windows.

"From an enthusiast point of view, 3GB is the minimum most should consider when choosing a kit. For a long while, 2GB was the recommended amount, but since two does not devide into 3 memory sticks, we're now at 3GB. The question is now, do you need 3GB or 6GB. If you are really rich, you can even get yourself a 12GB Triple Memory kit but be prepapred to sleep on the couch if the significant other was budgeting that joint bank account for something important like rent or food."
