I know this is a low-budget build, but personally speaking, I wouldn't want to run BF4 off of anything other than an SSD. In fact, it's the first game I've played that's convinced me that an SSD is pretty much required to play it, rather than just being a 'nice to have' option. Having initially tried running BF4 from a conventional hard disk, the load map load times are just awful. To start with, I thought my computer had hung it took so long to load! I would just save up for a little while longer & buy a 128Gb MX100 for about £50. Believe me, it'll be worth it!
