Is there going to be noticable difference loading those long load time levels in Battlefield 3 and 4? and DayZ?
Difference between what and what? Presumably you mean 'difference between a HDD and an SSD only connected to a SATA 3Gbps port', if so, yes, as even a brand-new WD Black tops out at about 180MB/sec if everything is in its favour, a decent SSD will do probably do something like 250/280MB/sec, maybe more when connected to a SATA 3Gbps port.
