My machine spec is as follows - i5 3570k @ 3.4ghz, 16gb of PC12800 RAM, Asus GTX 1050 ti 4gb graphics card and 2 SATA hard drives. I play a lot of games and think my machine should be running quicker than it is. Are the hard drives the thing that's slowest it down and should I upgrade to SSD drives? All help appreciated.
