The G Skill NT series has 2400mhz DDR4 RAM for less than 50 pound. I don't think there's anything to gain performance wise from more expensive RAM. The G.Skill NT series wll work with my gaming rig that includes the i7 6700k, Maximus Hero Viii, and Samsung 950 Pro so I'm happy. Question is, do I really need a metal heat spreader or is this kind of RAM fine for a 'high end' rig? Are the heat spreaders simply for show at significantly more cost?
