I've been doing this a long time and it still ocasionally confuses me. I was looking to buy some memory and came across some Mushkin PC3200. I found 2 different models from Mushkin that fits my needs, one is Mushkin Green and the other is Mushkin Enhanced. Spec wise, the 2 are identicle: 2X1GB, DDR3200, 3-3-3-8, 2.5V-2.7V. Mushkin Green is $149 while the Enhanced is $201. If I am not mistaken, these are both considered the "value" line of Mushkin RAM. I'm thinking I should save myself $52 and get the Mushkin Green. Whant do you think?
