So i already have a 128 gb ssd for OS and MS Office + Skyrim and a 1 TB HDD for all my other games and other things. I would like to move all my Games onto an independent drive. at the moment i have 15 games and that will increase in a few months. So my question is what do you thing would be a reasonable amount of space for a SSD purely for games + Steam? I am thinking of getting the Samsung 840 pro 256 GB but the 840 EVO 750 GB is around the same price as the 840 pro 512 GB. Any advice is appreciated.
