I'm looking at building a laptop for university work and some gaming, and I have the choice between two types of RAM: Kingston Hyper-X Genesis and Samsung. Both are 8GB (2x4GB), 1600MHz, SODIMM, DDR3, etc. However, the Kingston Hyper-X Genesis costs £10 more. I know this isn't a lot, but would there be any difference in performance between the two types? Has one been built better than the other? I just want to make sure I'm not spending £10 on a flashy name.
