Hi people, Looking at the 250GB size for an OS drive (games on another drive, so this would be general desktop apps etc). Is it really worth spending the extra on the 960 EVO M.2? I know the figures speak for themselves and the M.2 is quicker, but in real world terms is it REALLY going to be that noticeable and worth the 40% price difference (the 850 can be had for around £84)? Any help on the matter will be much appreciated.
