The 24" iMacs go for relatively cheap on craigslist in my area, around 800-1000 USD. I don't need the sandybridge iMac, and while it would be nice, 27" Screen is to big for me IMO and I only need to be running iMovie, Garageband, and FCP. To anyone who owns a 24" iMac, can you tell me how it performs playing Starcraft II? It is the only video game I play on PC, so if it can even run on low I'll be fine. Thank you!
