Hi folks, I just joined this great community! After eggenizing and reading a lot about Macs (still as a current PC user) I have my first questions: I am planning to buy a new Imac24 with 2.9 GHz, 1 TB HD, ATI HD 4850. I think this is a nice configuration, however I am not really sure about the following: a) does it make sense to buy this iMac? I have the feeling the graphics card is really "old" and not up-to-date. I also think that this graphic card is not a state of the art for a current IMAC. Is this the BEST graphics card you can get for a desktop mac? b) When was the last time the IMAC models were updated? Is there an upcomign release? c) I am not a gamer anymore. I work mainly with the Adobe products and because they are all available for MAC I want to leave the dark - blue-screen -PC world far behind me . So maybe I can just go for a low end IMAC with 2.6 GHz and the lowest graphics card option. What do you gus think? If I'd play a game then probably more a driving/race simulation than a 3D shooter. But if the HD 4850 card is outstanding compared to all other MAC graphic cards I would still consider buying it. d) How complicated is it to exchange a hard-drive in an IMAC by myself? I have no problems building new PCs from scratch but I never touched a mac. Is it also so easy or much more complicated? Thank you guys. I look forward hearing your thoughts!
