Could I plug my gaming PC into a mid 2010 imac? Would that be stupid or a good blend of mac and upgradable gaming pc? I have an okay 20" dell display, but this would allow me to get a mac and a nicer display for my gaming. Im trying to decide weather to do the imac or a macbook pro. Any pros and cons or suggestions? I dont need much portability, but a nice laptop would be nice in the long run, but so would an imac with a super nice display.
