to answer your questions yes, it should work pretty well for unity dev. seems like a good price for a labby with those stats.
what OS is on the machine? make sure its 64 bit or ur only using up to 3 gigs of ram. 8 gigs i believe is the max for ram on lappys at the moment. if u want a huge powerhouse a desktop is the way to go. im running 12 gigs and can get up to 24.
what you have posted is great but if you find yourself starting to lag while in dev, expansion on your hardware will be harder because of the limitations of a notebook compared to desktop
I saw a few laptops that claim they will support up to 32gb of RAM. 8gb may seem like a lot, but I’m thinking about the long term. I can’t afford to buy a new computer every year or two. Having the ability to install more than 8gb may mean I’ll be able to run Windows 9 when it’s released in a few years. I usually keep my computers about four years.
