I dreadfully need an external harddrive for my laptop as I've packed the thing full. I was thinking of getting one and putting my games on it. I play quite graphic intensive games such as bioshock, assassins creed, half life, the witcher, crysis, and stuff like that. I payed a lot for my laptop lol. My question is if I were to get a external hard drive and install my games would playing them off that affect their performance enough to discourage the use of an external hard drive for that?
