In your opinion, which is better, if they're both 1600 and the price are the same?
One 8 GB is better if you're considering for an upgrade in the future. But two 4 GB has a slight performance difference running in Dual Channel. Anyway, if you have a particular model in mind, you can check the prices and all those stuff at this website: memorystock.com
Good luck!
