Nah, you need it.... Its essential. I can't believe I was ever strolling around with 4 RAM in my head. You can't even effect some of the leveled up enemies and defense systems with less than 6 some times. Plus it gives you a bigger buffer (more sequence selections) in the hacking minigame thing. Makes it possible to easily lock up all 3 datamining options - not just one. Having more than just two quickhacking options is a necessity too.
When I'm sneaking into a compound I got 4 or 5 hacks going at once sometimes. It'll pay for itself faster than anything else. Just opens up so much of the game... I had it before doing the first heist and I can't imagine doing it with the standard version.
shyt, its actually dope too because in some of the boss fights I'll be having a sword fight while having a quickhack fight at the same time
