Hi everybody! I'm a graphic designer happily working with his mid 2007 2,8 ghz iMac. In the evenings or weekends however I like to play some games. A little World of Warcraft in OS X and Bioshock, Medal of Honor Airborne etc. via Bootcamp. I hope to play Starcraft 2 once it's released, and whatever seems interesting in the months ahead. I upgraded my iMac to 4 gb ram and have the 3 years warranty. Now my question is, should I sell this machine for exactly the same new one for the 8800 gs gfx card? The base 2,8 ghz iMac is now 1600 in Europe, with the 2600 hd pro and a 320 gb hd. My machine would have a 500gb hd + the 3 years warranty, so I guess I could get at least 1550 for it. It's condition is like brand new, I always treat my babies well. The new 2,8 ghz model with the 8800 gs and a 500gb hd would cost me 1750 , so I imagine it would be something around 200 to upgrade. Obviosly I could use 4gb ram in my new machine too. The difficult part could be to find a local buyer so I could keep my present machine to do my work until the new one arrives, and maybe get some money in advance. But I'm sure I'll find a sollution if I look around. Please don't suggest a mac pro, it was and is out of my budget since I'm also saving for a new mbp to replace my powerbook next year. Thanks for any comments!
