What is the STRAIGHT scoop on how much memory a late '08 15" uniMBP with LED Cinemax running will be able to use with Snow Leopard....or in the near future? Currently, I have 4g's and often have Parallels running with Windows Vista for my trading platform running 24hrs. I use OSX for EVERYTHING else. When running Vista it seems to get VERY close to using all 4 gigs (realistically 3+gigs). I also have a MacMini with 4 gigs running a LED screen with the same issue. Should I just get a 6 gig upgrade or do a full 8? I'm afraid I'll have to anti up and get a MacPro with 3 graphic cards to run 3 screens and keep my MBP as my mobile trading solution. What's the STRAIGHT scoop?
