Hello guys. I just wanted to know which is better to get, 1x4gb 1600mhz or 2x2 1333mhz? I'm going to use an APU and they also said that ram would affect the performance of an APU. but i'm in a tight budget. 2x2gb 1333 is much cheaper here. i know 1x4gb can be upgraded but i will upgrade it after a few months so it will take long. i would like some suggestions. thank you.
