or should I buy the R9 M395X 2096mb?? - I'm looking at a couple of different slightly used I macs with these different cards the one with the better card also has a 4 ghz processor compared to a 3.5 processor but the better one has less only 1/2 TB storage. I know my son had complained that our OLD Imac couldn't play any "decent" games. I'd rather buy the cheaper Imac with more storage but if it can't play a decent game I might cough up the cash. Thanks for the time.
