Hi i’m going to get an MSI dominator for AE with 32gigs RAM and SSD. What do you guys think will be better, the 880m with 4800mq OR 870m with i7-4940MX which will cost $300 more? do you think the extra processing power is worth the $300 and having to get a lower GPU? (I can’t afford an 880m with 4940MX) thanks
